Calculation of the daily intake of calories and bju. How to calculate how much wallpaper you need

From the size of the room (more on that below) and from the design. One roll is usually 10 meters. If the wallpaper is plain and the ceiling height is 2.5 meters, you can cut the roll into four strips. If the pattern has to be customized, there will be three stripes.

stroyday.ru

No alignment of the pattern: the roll is simply cut into the desired number of panels. Usually this plain wallpaper, wallpaper with an abstract pattern or vertical stripes.

stroyday.ru

The pattern will have to be aligned horizontally so that adjacent stripes start with the same elements. And here everything will depend on the height of the rapport - the distance through which the pattern repeats (indicated on the label). In the worst case, you will have to throw out almost the entire height of the rapport, so when calculating it, you need to add it to the height of the ceiling.

stroyday.ru

The pattern is located diagonally, so each canvas is shifted. As a rule, half rapport. In this case, the height of the rapport and the amount of offset must be added to the height of the ceiling: you will find both numbers on the label.

How to calculate the number of wallpapers using tables

it perfect way if the room is square or, and the wallpaper does not require adjustment. You only need the area of ​​\u200b\u200bthe room and the height of the ceiling.

How to calculate the number of wallpapers mathematically

If the room has complex shape, there are bends and niches, it is better to count along the perimeter. To do this, add the lengths of all the walls. Window and doorways less than 60 cm wide are treated as flat wall, wider ones are excluded from . The resulting value is rounded up.

Example: 2.75 m + 3 m + 0.4 m + 2.85 m + 4 m + 0.65 m = 13.65 m ≈ 14 m.

Then you need to determine the number of strips: divide the perimeter by the width of the roll. Let's go back to our example: 14 m / 1.06 m = 13.2. Rounding up - 14 canvases of wide wallpaper. For narrow wallpapers: 14 m / 0.53 m = 26.4. That is 27 bands.

Now you need to determine how many strips can be obtained from one roll: the length of the roll must be divided by the length of the strip. And there can be three options:

1. If the wallpaper does not require adjustment, the length of the strip is equal to the height of the ceiling. 10 m / 2.75 = 3.6 ≈ 3.
2. If the wallpaper is with a straight joint, the length of the strip is equal to the sum of the ceiling height and the rapport height (0.6 m). 10 m / (2.75 + 0.6) = 2.9 ≈ 2.
3. If the wallpaper is with a combined joint, the length of the strip is equal to the sum of the ceiling height, the repeat height (0.6 m) and the offset value (0.3 m). 10 m / (2.75 + 0.6 + 0.3) = 2.7 ≈ 2.

The last step: we divide the number of strips we need by the number of strips in the roll. If the wallpaper is wide, 14 should be divided by 3 or 2. If narrow, divided by 3 or 2 will need 27 stripes.

How to calculate the number of wallpapers using services and applications

Most fast way, if you know the parameters of the room, and the easiest, if you are not friends with mathematics. There are plenty of wallpaper calculators on the web, here are just a few good ones.

• Wallpaper calculator from calc.by. It counts both by area and perimeter, allows you to exclude door and window openings from the calculation. You can also set the width and footage of the roll.
• Wallpaper calculator from calc.ru. Calculates the perimeter. Helps determine how much wallpaper and glue is needed.
• Wallpaper calculator from remont-online.com. First, the configuration of the room is selected, then the width of the walls and wallpaper is driven in. You can also specify the price per roll to find out the final cost of pasting.

If you are already in the store, use the application for calculations. Here are two free ones with a good rating. non-food products of good quality, not subject to return or exchange, there are finishing materials. But we are talking only about goods sold by the meter.

The wallpaper remained unopened, not dented or scratched.

No more than 14 days have passed since the purchase. When buying online - 7 days.

There is a receipt or other document confirming the fact of purchase. If the check is not preserved, you can request a cash tape (stores keep it for a month) or involve witnesses.

In other words, if you don't like the wallpaper, you can take it back to the store. All rolls. In this case, the seller will offer you a similar product, and if there is none, you can write a request for a refund.

It will be problematic to return one or two extra rolls after. But large stores usually go to meet customers. After all, they buy wallpapers in large quantities, and plus or minus one roll does not particularly affect the sale. Customer loyalty is more valuable.

Just in case, check the terms of the return before buying.

Despite the fact that the range of materials for the repair and decoration of houses and apartments is replenished almost every year with one or another novelty, wallpaper does not lose its “leadership positions” and still remains, probably, the most popular way to decorate walls in residential premises. Moreover, the widest variety modern wallpaper, made using the most advanced technologies, allows you to finish in any interior style, authentically imitate wall cladding with many natural materials. And if we add here the relatively low cost and the possibility of independent finishing works, then the popularity of wallpaper gets a completely logical explanation.

Before the owners of housing, who have decided in favor of such a finish, the question will surely arise - how to calculate how much wallpaper is needed per room? We will try to help them with this - below is a convenient online calculator.

For those readers who have already been pasting wallpapers and, therefore, “savvy” theoretically, there should not be any problems using the program. Beginners may have unclear questions - some explanations on the use of the calculator and on the basic principles of calculation are given below.

Options for the selected wallpaper

Modern wallpapers amaze with their diversity. They differ in the material of manufacture of the base and the front layer - they are paper, non-woven, vinyl, based on fiberglass, made from natural natural materials(bamboo, cork), or their textiles. Their external design is also presented in the widest assortment. But in the context of this article, for the most part, we are only interested in dimensional parameters and the type of applied pattern. Let's start with the sizes.

Standard wallpaper roll sizes

First you need to correctly put down the linear dimensions of the wallpaper you like. They must match existing standards(with a minimum error) - these parameters are usually indicated on product labels on each roll.

• It is immediately noticeable that the wallpaper is installed by default in the calculator, the roll of which has dimensions of 53 × 1005 cm or 0.53 × 10.05 m (note: the length is not 10 and a half meters, namely 10 meters + 5 centimeters - this is very common allowable error in the calculations).

Indeed, this standard is the most common. It is believed that it is with such narrow canvases that it is most convenient to work with novice finishers. In this size range you can find any type of finish.

• The next in terms of the variety of options presented can be called the standard 106 × 1005 cm. In fact, these are the same wallpapers, but doubled in width. It is clear that pasting the wall in this case is faster, but working with wide canvases will require more practical skills. However, many masters claim that it is easier for them to finish with just such a wide standard.
• Quite often there are imported wallpapers with a width of 74 cm. The length of the roll in this case is usually 10 m.
• Wallpapers with a width of 60 cm, 120 cm, 150 cm are very rare, but such standards exist, so they are also given attention in the calculator.
• In addition, the wallpaper can vary in the thickness of the canvas - from super-thick with a vinyl embossed pattern to thin non-woven or fiberglass - for painting. Accordingly, variation along the length of the roll is not excluded, while maintaining its standard width. So, on sale you can find, in addition to the mentioned 10.05 m, rolls with a length of 5, 8, 12, 15, 18, 20 and 25 meters. This variety is also provided in the calculator.

Pattern type and rapport size

It would seem that everything is simple: there is a standard roll length, wall height, and it is easy to determine how many canvases will be obtained from each roll. But it is not so.

Firstly, right technology wall decoration with wallpaper assumes that the canvas is cut with a mandatory allowance from above and below, which, after gluing, is carefully cut with a sharp knife along the baseboards (floor and ceiling) or along the intended line. This means that at least 50 mm must be added to the length of each web.

Secondly, another parameter interferes with the calculation process - the type of pattern and the need to combine it. There may be various options here.

• Wallpaper design does not require matching pattern.

This is the simplest option - the canvas can be cut from any point on the roll, that is, there are no small scraps left. A typical example is vertical lines, any formless streaks, toning or relief of a chaotic order, etc.

• An infrequent variety is wallpaper, each canvas of which, when pasted, should take the opposite direction.

This is a wallpaper usually with vertical lines, and the need for a reverse is due only to the peculiarity of the arrangement of the stripes.

You can also cut out such canvases from any point.

• More difficult case- the details of the drawing require mandatory alignment. But at the same time, the shift of the canvases is not required, since the pattern is oriented horizontally.

The height (step) of the drawing has its own name - rapport. So, when cutting such rolls, the option is not ruled out that in order to mark the beginning of the next canvas, it will be necessary to remove a strip close to the rapport value in trimming. Naturally, this may affect the number of whole canvases from one roll.

At the same time, each of the canvases starts from approximately the same point, tied to the drawing.

• Finally, another option - the drawing also requires adjustment, but due to its diagonal location, each next canvas is shifted vertically by a certain amount (usually half the rapport).

Very often, novice masters make the most mistakes with such wallpapers.

It is clear that even with such cutting, almost a whole rapport can go into trimming with an unfavorable outcome.

On commodity labels of wallpapers that require pattern alignment, a pictogram is usually applied, which indicates the rapport (in the numerator) and the amount of pattern offset (in the denominator).

So, in order not to be mistaken with the number of wallpapers, the length of the roll, when determining the number of finished canvases, must be divided not only by the height of the wall, but also taking into account the allowance (min. 50 mm) and rapport.

The main parameters of the room

The main parameters of the room for calculations will be the perimeter and height. A few more words.

• It is not difficult to measure the perimeter, for example, by walking along the walls with a tape measure. The easiest is in rectangular room. A little more difficult - indoors irregular shape, but also special difficulties should not cause. If the room has niches or ledges that will also be pasted over with wallpaper, then their perimeter must be taken into account.

The perimeter is entered into the calculator in full (or the full length of the wall to be pasted over with wallpaper, if a diverse finish is expected).

• An important point: windows and doors - should they be taken into account when determining the amount of wallpaper?

Required here individual approach. Agree that the door can be only 600 - 800 mm wide, and then when calculating it, you can simply “not notice” it as a flat wall.

But the door can be two- or even three-leaf, one and a half meters wide or more - it probably makes sense to exclude such an opening from the calculations. The situation is similar with windows. In this variant, the width of the window and doorways it will be possible to subtract from the perimeter of the room - the remaining trimmings and the created reserve are usually more than enough to seal the areas above the doors, above and below the windows. This is especially true for wallpaper with a combination of patterns - when cutting, very long canvases often remain.

• And the last parameter is the height. Often, the concept of "ceiling height in a room" appears in instruction articles. This does not seem to be entirely true - skirting boards are often placed on top and bottom of the wall, which “eat up” a certain height. In addition, wallpaper may not be glued to the entire wall, for example, with complex finishing. various materials(or even several types of wallpaper). It is probably more correct to operate with the concept of the height of the pasted section of the wall. It is entered into the calculator in its “pure form” - without adding any allowances or offsets to fit the pattern.

Now you can go directly to the calculations with all knowledge of the matter. But one more small addition: it is recommended to always purchase at least one roll in reserve - situations are different. This is also taken into account in our calculator.

And finally, to help the novice master - a small video sketch with tips on choosing wallpaper:

The results of BMI calculations are not suitable for assessing the weight of professional athletes, pregnant women, as well as people suffering from edema and other disorders that lead to misjudgment initial data.

Weight ranges in this calculator are calculated taking into account height, according to the methodology of the World Health Organization (WHO).

The very method of estimating weight by BMI is intended for the primary detection of underweight or excess weight. Obtaining an estimate different from the norm is the reason for contacting a nutritionist and endocrinologist in order to conduct an individual weight assessment and make recommendations for its correction, if necessary.

The range of ideal weight (norm) shows at what weight the probability of occurrence and recurrence of diseases associated with overweight or underweight is minimal. In addition, as practice shows, a person with normal weight looks not only healthy, but also the most attractive. If you adjust your weight, it is highly recommended not to go beyond the norm, in order to avoid health problems.

About weight categories

underweight usually an indication for increased nutrition; consultation with a dietitian or endocrinologist is also recommended. This category includes people who are malnourished or have a disease that leads to weight loss.
Underweight is also typical of professional models, gymnasts, ballerinas or girls who are overly fond of weight loss without the control of a nutritionist. Unfortunately, this can sometimes lead to health problems. Therefore, weight correction in this range should be accompanied by regular medical supervision.

Norm shows the weight at which a person has the maximum chance of staying healthy as long as possible, and, as a result, beautiful. Normal weight is not a guarantee of good health, but it significantly reduces the risk of disorders and diseases caused by overweight or underweight. In addition, the owners of normal weight, as a rule, are in good health even after intense physical exertion.

Preobesity speaks of being overweight. A person in this category often has some signs associated with excess weight (shortness of breath, increased blood pressure, fatigue, fat folds, dissatisfaction with the figure) and has every chance of moving into the category of obesity. AT this case slight correction of weight to normal, or to values ​​close to it, is recommended. It also does not hurt to consult a nutritionist.

Obesity- an indicator of chronic disease associated with excess body weight. Obesity invariably leads to problems with the cardiovascular system and significantly increases the risk of acquiring other diseases (diabetes, hypertension, etc.). Obesity is treated exclusively under the supervision of a nutritionist or endocrinologist, and only after the necessary tests have been carried out and its type has been determined. It is not recommended to engage in uncontrolled diets and serious physical exertion for obesity, as this can provoke additional problems.

Answers on questions

What is the ideal weight for me?

The calculator calculates a weight range that is ideal for you based on your height. From this range, you are free to choose any specific weight, depending on your preferences, beliefs and requirements for the figure. For example, adherents of a model figure tend to keep their weight on the lower border.

If your priority is health and longevity, then ideal weight calculated from data medical statistics. In this case, the optimal weight is calculated based on a BMI of 23.

Can you trust the resulting estimate?

Yes. Adult weight estimates are based on the results of authoritative research by the World Health Organization (WHO). Weight assessment from birth to 18 years is made on a separate basis. special technique also developed by WHO.

Why is gender not taken into account?

The BMI of adults is assessed in the same way for both men and women - this is justified by the results of statistical studies. At the same time, for weight assessment, gender and age are of fundamental importance.

Some other weight calculator gives a different result. What to believe?

Exists great amount calculators designed to estimate weight based on height and gender. But their formulas, as a rule, were developed in the last century by individuals or groups based on criteria that are unknown to you or do not suit you (for example, formulas for evaluating athletes).

The WHO recommendations used in this calculator are based on common modern people, subject to conditions modern life, advances in medicine and based on recent observations of the population of all continents of the planet. Therefore, we trust only this technique.

I think the result should be different.

Evaluation is based solely on the height and weight you provide (and age and gender for children). In case of unexpected results, please double-check all entered data. Also, make sure that you do not belong to any of those whose weight cannot be assessed through the body mass index.

My result is underweight, but I want to lose more weight

This is not unusual, many professional models, dancers, ballerinas do just that. However, in this case, it is recommended to lose weight only under the supervision of a nutritionist and endocrinologist, so as not to harm your health. if it means something to you.

My result is normal, but I consider myself fat (or thin)

If you have concerns about your figure, then we recommend that you go in for fitness, having previously consulted a good nutritionist.

Please note that some elements of the figure are almost impossible to correct only with the help of fitness, exercise, diet, or a combination of both. Your goals should be analyzed by an experienced doctor in order to assess their reality, consequences and prescribe only the right procedures.

My result is pre-obesity (or obesity), but I do not agree with this

If you are an athlete with a high muscle mass, then the BMI weight estimate is simply not intended for you (this is mentioned in). In any case, for an accurate individual weight assessment, contact a nutritionist - only in this case you will receive an authoritative result with a doctor's seal.

Why am I considered too thin or fat even though my weight is normal?

Pay attention to the personality and weight of those people who bother you. As a rule, they judge exclusively by themselves: subjectively. Fat people always consider thin people to be skinny, and thin people consider fat people to be fat, moreover, both of them can have a healthy weight. Take into account and social factors: try to exclude or stop those judgments in your address that are based on ignorance, envy or personal hostility. Only an objective assessment of BMI is worthy of trust, which clearly indicates the norm, excess or deficiency of mass; and trust your anxieties about the figure only to supportive people of your weight category or a doctor.

How to calculate body mass index (BMI)?

It is necessary to divide the weight indicated in kilograms by the square of the height indicated in meters. For example, with a height of 178 cm and a weight of 69 kg, the calculation will be as follows:
BMI = 69 / (1.78 * 1.78) = 21.78

Good day!

Interest, I tell you, is not only something "boring" in mathematics lessons at school, but also an archa-necessary and applied thing in life (found everywhere: when you take out a loan, open a deposit, calculate profit, etc. ). And in my opinion, when studying the topic of "interest" in the same school, extremely little time is devoted to this ().

Perhaps because of this, some people find themselves in not very pleasant situations (many of which could have been avoided if they had time to figure out what was there and how ...).

Actually, in this article I want to analyze the most popular tasks with percentages that just occur in life (of course, I will consider this as much as possible plain language with examples). Well, forewarned means forearmed (I think that knowledge of this topic will allow many to save both time and money).

So, on to the topic...

Option 1: calculating prime numbers in your head in 2-3 seconds.

In the vast majority of cases in life, you need to quickly figure out in your mind how much it will be a 10% discount from some number (for example). Agree, in order to make a purchase decision, you do not need to calculate everything down to the penny (it is important to figure out the order).

The most common variants of numbers with percentages are listed below, as well as what you need to divide the number into to find out the desired value.

Simple examples:

• 1% of the number = divide the number by 100 (1% of 200 = 200/100 = 2);
• 10% of the number = divide the number by 10 (10% of 200 = 200/10 = 20);
• 25% of the number = divide the number by 4 or twice by 2 (25% of 200 = 200/4 = 50);
• 33% of the number ≈ divide the number by 3;
• 50% of the number = divide the number by 2.

Problem! For example, you want to buy equipment for 197 thousand rubles. The store gives a 10.99% discount if you meet any conditions. How can you quickly figure out if it's worth it?

Solution example. Yes, just round these couple of numbers: instead of 197, take the amount of 200, instead of 10.99%, take 10% (conditionally). In total, you need to divide 200 by 10 - i.e. we estimated the size of the discount at about 20 thousand rubles. (with a certain experience, the calculation is done practically on the machine in 2-3 seconds).

Exact calculation: 197 * 10.99 / 100 \u003d 21.65 thousand rubles.

Option 2: use the Android phone calculator

When you need a more accurate result, you can use the calculator on your phone (in the article below I will give screenshots from Android). Using it is quite simple.

For example, you need to find 30% of the number 900. How to do it?

Yes, it's quite simple:

• open calculator;
• write 30%900 (of course, the percentage and the number can be different);
• note that at the bottom under your written "equation" you will see the number 270 - this is 30% of 900.

Below is more complex example. Found 17.39% of the number 393,675 (result 68460.08).

If you need, for example, subtract 10% from 30,000 and find out how much it will be, then you can write it like that (by the way, 10% of 30,000 is 3000). Thus, if 3000 is subtracted from 30,000, it will be 27,000 (which is what the calculator showed).

In general, very handy tool, when you need to calculate 2-3 numbers and get accurate results, up to tenths / hundredths.

Option 3: we calculate the percentage of the number (the essence of the calculation + the golden rule)

It is not always and not everywhere possible to round numbers and calculate percentages in your mind. Moreover, sometimes it is required not only to get some exact result, but also to understand the very "essence of the calculation" (for example, to calculate a hundred/thousand different problems in Excel).

Let's say we need to find 17.39% of the number 393,675. Let's solve this simple problem...

To remove all points on "Y", consider the inverse problem. For example, how many percent is the number 30,000 of the number 393,675.

Option 4: calculate percentages in Excel

Excel is good in that it allows you to make fairly voluminous calculations: you can simultaneously calculate dozens of various tables by linking them together. And in general, can you manually calculate the percentages for dozens of items of goods, for example.

Below I will show a couple of examples that are most often encountered.

The first task. There are two numbers, for example, the price of buying and selling. We need to find out the difference between these two numbers as a percentage (how much one is more / less than the other).

For a more accurate understanding, I will give another example. Another problem: there is a purchase price and the desired percentage of profit (let's say 10%). How to find out the selling price. Everything seems to be simple, but many "stumble" ...

Additions on the topic are always welcome...

That's all, good luck!

Using the percentage calculator you can make all kinds of calculations using percentages. Rounds results up to the right amount decimal places.

The calculator is designed specifically for calculating percentages. Allows you to perform various calculations when working with percentages. Functionally consists of 4 different calculators. Examples of calculations on the percentage calculator, see below.

A percent in mathematics is called a hundredth of a number. For example, 5% of 100 equals 5.
This calculator will allow you to accurately calculate the percentage of a given number. Available various modes calculation. You can make various calculations using percentages.

• The first calculator is needed when you want to calculate the percentage of the amount. Those. Do you know the meaning of percentage and amount
• The second is if you need to calculate what percentage is X of Y. X and Y are numbers, and you are looking for the percentage of the first in the second
• The third mode is adding a percentage of the specified number to the given number. For example, Vasya has 50 apples. Misha brought Vasya another 20% of the apples. How many apples does Vasya have?
• The fourth calculator is the opposite of the third. Vasya has 50 apples, and Misha took 30% of the apples. How many apples does Vasya have left?

Frequent tasks

Task 1. An individual entrepreneur receives 100 thousand rubles every month. He works on a simplified basis and pays taxes of 6% per month. How much does an individual entrepreneur have to pay taxes per month?

Solution: We use the first calculator. Enter the bet 6 in the first field, 100000 in the second
We get 6000 rubles. - amount of tax.

Problem 2. Misha has 30 apples. 6 he gave to Katya. What percentage of total number Did Misha give apples to Katya?

Solution: We use the second calculator - enter 6 in the first field, 30 in the second. We get 20%.

Task 3. At Tinkoff Bank, for replenishing a deposit from another bank, the depositor receives 1% on top of the replenishment amount. Kolya replenished the deposit with a transfer from another bank in the amount of 30,000. What is the total amount Kolya's deposit will be replenished with.

Solution: use the 3rd calculator. Enter 1 in the first field, 10000 in the second. We press the calculation, we get the amount of 10100 rubles.
