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.

To "blind" perfect figure would require a significant amount of time and effort. However, before embarking on this difficult task, go to the mirror and look at yourself critically, but with love. You can take a centimeter and measure all your circumferences, just don't draw any gloomy conclusions if you don't get 90-60-90.

Most likely, it really will not work out, but there is no tragedy in this. First, there are many things that can be fixed. Secondly, a lot of things may not need to be corrected.

Type of constitution

For example, anthropologists distinguish three main types of constitution (not to mention numerous transitional and intermediate variants). These three types are called: normosthenic, hypersthenic and asthenic.

A person with a hypersthenic constitution, most often of average or below average height, broad-boned, with relatively short arms and legs and a wide chest. Asthenik is tall, long-legged, with a narrow chest, as if directed upwards. Normostenik means “normal”: growth is average and everything else too.

You can quite accurately determine your constitutional type by the so-called intercostal angle, which is formed by the lowest costal arches. Stand in front of a mirror with your stomach in and out chest, and see what your intercostal angle is (you can even take a large protractor and measure).

If it is approximately 90 degrees, then you are normosthenic. If this angle is sharp, less than 90 - you are asthenic, and if obtuse - hypersthenic. In the latter case, in particular, the successful disposal of excess weight can lead to a not very successful result: thinness will not decorate the hypersthenic, and some “excess” weight, on the contrary, will round off the somewhat square outlines of the figure.

Ideal weight is not a number on the scale, but an integral important component of your life.

Ideal weight

Your weight is ideal if:

• It does not cause health problems (or potential risks);
• It does not restrict you Everyday life, desires and needs;
• You are satisfied with your body as it is, and at the same time you do not feel embarrassed;
• You like your body and don't compare yourself to the people around you (or actors, singers, athletes, etc.).

There are various indicators and formulas that can determine the approximate weight range in which you may begin to develop health problems, as well as the weight you need to strive for in order to minimize or completely eliminate these problems.

Methods for determining excess weight

1. Determination of excess weight using scales

The simplest (and most approximate): height (in centimeters) minus 110. The resulting number (in kilograms) is ideal weight. However, this does not mean that “everything else” is superfluous.

There is the easiest and most accurate way to determine if you are overweight: just measure the crease on your stomach. For women, the allowable norm is 2-4 cm, but for men it is slightly less - 1 - 2 cm. Experts say that from 5 cm or more is obesity. True, unfortunately, the exact result, how much we need to lose, in this case we won't see. This is just a kind of hint that it's time to sit down at the simulators and on a diet.

3. BMI - body mass index (Body Mass Index)

The so-called body mass index (BMI) has received general recognition. His calculation: Divide your weight in kilograms by your height in meters squared. Example: BMI \u003d 68kg: (1.72m x 1.72m) \u003d 23. This formula is good because it works for both “kids” and “giants”.

The following BMI values ​​are distinguished:

less than 15- acute weight loss;
from 15 to 18.5- weight deficit;
from 18.5 to 24 - normal weight;
from 25 to 29- overweight;
from 30 - 40- obesity;
over 40- severe obesity.

5. Scales that determine the percentage of body fat

But BMI does not speak about the distribution of kilograms on the body. Physique matters. With the same height and weight, one person will be slim and strong, the other full and loose. The ratio of muscle and fat is important, how many percent of the total body weight is fat mass, how much is muscle and bone, how much is water. The normal proportion of fat in the body of men is 12-18%, women - 18-25%.

Recently, devices have appeared to determine the percentage of body fat. In the process of bioelectrical analysis, a weak, absolutely safe substance is passed through the body. electricity. The principle of analysis is based on the fact that an electrical impulse passes more easily through muscles and water than through fat. Now scales have appeared that include this technology, you can use them to regularly and more or less accurately measure at home not only your weight, but also the percentage of fat.

6. The formula for determining the realistically achievable weight

The formula is applicable for cases when a person begins to lose weight with a fairly large weight.

The calculation is carried out in two stages:

1. First determine your weight, as if you were the owner of a normal metabolism:

(45 kg) + (1 kg for each centimeter of height over 150 cm) + (0.5 kg for each year over the age of 25, but not more than 7 kg).

2. Then carry out a correction for a slow exchange:

Add from 4.5 to 7 kg;

Add another 4 to 7 kg (with an initial weight of about 90 kg);

A few more kilograms are added (with the initial weight, greatly exceeding 100 kg).

An example for a fifty-year-old lady with a height of 158 cm, weighing 90 kg today:

45 kg + 1 kg (158 cm - 150 cm) + 7 kg + 7 kg + 7 kg = 74 kg.

If our lady manages to bring herself up to 60 kg, then she is provided with all sorts of health troubles and an inevitable quick return to her original weight, plus a certain number of cheerful kilograms.

How does body weight affect health?

What does the number on the scale really mean? How does it relate to all the reasons why you want to lose weight? Perhaps you want to look more attractive, improve your health, fit into your favorite jeans or put on a beautiful dress that has been hanging in the closet for many years, improve your physical form, return to youth, or is it just more comfortable for you to live with fewer kilograms? The number on the scale is not what determines your success or failure. There are so many ways to measure progress and success besides constantly monitoring the scale.

There is only one reason to talk about "normal" or "ideal" weight and that reason is your health.

Which can later lead to serious illness or even death. Although your specific weight may not be the cause of any diseases, it is absolutely known that people whose weight is above or below the "norm" are much more susceptible to various problems with health.

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. In this case, a slight weight correction to the norm, 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 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 life expectancy, then the ideal weight is calculated based on the 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

Seven times measure cut once. You can’t argue with folk wisdom, especially when you need to independently calculate the wallpaper for the room.

The pieces left from the panels, and even more so the extra rolls, are practically not suitable for anything (yes, we always leave them “in reserve”, but as a rule we rarely use them). On the other hand, if you buy more wallpaper, you can get into a mess. After all, the shade wallpaper sometimes differs from batch to batch.

So the rational owners are faced with the question of how much wallpaper to buy, so that it is enough for pasting, and there are no extra meters left.

Working with the program is more than simple, the calculation formula is intuitive, it is enough to indicate the dimensions of the room and the characteristics of the wallpaper. But, I would like to draw your attention to a few nuances.

How to calculate how much wallpaper you need per room

• length, width and perimeter of the room. If you have a simple room configuration, specify its length and width. And if complex, then the perimeter;

• wallpaper width. The working width is indicated, because there are still wallpapers that need to be glued with an overlap;

• rapport- the basic element of the ornament on the wallpaper canvas.

• bias. Shows how much the rapport on the wallpaper is shifted. Usually, this value is indicated on the roll. The desired length of the strip will increase by the same amount.

• the height of the room is indicated with a margin of 5 cm. This is necessary to avoid the lack of length of the strip of wallpaper with a difference in heights and a reserve for a beautiful cut.

Please note that windows and doors are not subtracted from the perimeter of the walls, because their location affects the order of wallpapering. If necessary, you can do it yourself. The material was prepared for the site www.site

Wallpaper table - calculation of wallpaper consumption according to the scheme

In addition to the calculator, they use a method - calculating wallpaper according to a table with standard parameters. Of course, the results are approximate and it is better to add an additional roll to the amount obtained.

Table number 1 - calculation of the number of rolls of wallpaper half a meter wide

Roll width half a meter (0.52 cm) and length 10 meters (10.05 m)

Table No. 2 - calculation of the number of rolls 70 cm wide

Roll width 70 cm (0.68 m) and length 10 meters (10.05 m)

Table number 3 - calculation of the number of wallpapers one meter wide

Roll width 1 meter (106 cm) and length 10 meters (10.05 m)

Sometimes the length of the wallpaper can reach 15 meters, so the calculations will have to be adjusted to the available length.

Calculator for calculating wallpaper for a room

Below is a program - an online wallpaper calculator that will help determine the consumption of wallpaper: paper, vinyl, non-woven, textile and fiberglass.

Construction begins with a project. Even small structures are recommended to be sketched on paper first, so that you can clearly see the proportions and estimate the consumption of materials. For major buildings design and estimate documentation made by professionals, but when building a private house, cottage, fence or garage, you can get by online calculators or ready-made solutions. The most important issue in the construction of structures is the construction of a reliable foundation, and therefore the question of how to calculate the amount of concrete per foundation is paramount.

26590

It is not difficult to calculate concrete for a foundation if there is certainty with the size and type of structure. The type of foundation and its dimensions should be determined by an experienced builder, based on the characteristics of the building under construction, the type of soil and the depth of its freezing in the area.

Tape

The most popular basis for the construction of a private house is considered a strip foundation. It is a kind of closed concrete strip that runs under all the load-bearing walls of the building.

How to calculate how many cubes of concrete are needed for the foundation? Calculators to help determine consumption cement-sand mortar for pouring, are available on many sites with a construction theme, one of these is presented at the end this material. To calculate the volume in cubic meters, you need to know the linear dimensions of the structure: height, width and overall length grounds.

Concreting of the strip base occurs by pouring the finished cement-sand mixture into wooden formwork with pre-installed reinforcing mesh. Large fractions (gravel, crushed stone) are added to the solution to acquire higher strength characteristics foundation.

The dimensions of the base depend on the dimensions of the building to be erected. Typically, the width of the foundation tape has a size of at least 300 mm, the height of the ground part is from 400 mm, and the depth can reach 1500-2500 mm, depending on the availability ground water, the depth of freezing and the desire to equip the basement. Strip foundations it is not recommended to install on heaving soils if the formwork is deepened less than the freezing depth.

For middle lane, when building small private houses and baths, it is enough to perform a deepening within 1500 mm with a height of the ground part up to 400 mm.

The length of the foundation will be equal to the total length of all external walls, including the internal bearing wall, under which the base is also installed. As a result, having received all the required values, it is possible to calculate the volume of concrete for the foundation. In this case, a calculator may not be required - just multiply all the indicators in meters and get the desired number in cubic meters.

The calculation formula looks like this:

V=h*b*l, where:

• V is the volume of the solution in m 3;
• h is the height in m;
• b - width in m;
• l is the length of the tape in m.

For example, for a building measuring 6x6 m and one internal bearing wall, with a foundation height of 2 m and a width of 0.4 m, the volume of the solution for pouring will be: V=2*0.4*30=24 m 3. With the same width and height of the foundation, for a house measuring 10x10 and two carriers interior walls, the calculation would look like this: V=2*0.4*60=48 m 3.

This calculation allows you to calculate almost the exact cubature of the solution, but it should be remembered that during transportation, part of the concrete is lost, and also with loose formwork, part concrete mortar can leak, but there is additional internal volume occupied reinforcing cage. Therefore, it would be correct to introduce a correction factor in the direction of increasing the calculated value by 2%.

As a result, we obtain a more accurate formula for calculating the volume of concrete for a strip foundation:

V=h*b*l + 0.02*(h*b*l)

The resulting value is rounded up to an integer. For our examples, the refined calculation will look like this: for a 6x6 house V=24+0.02*24=24.48 (25) m 3, for the house 10x10 V=48+0.02*48=48.96 (49) m 3.

slab

The slab foundation is a solid monolithic base under the building spot. For its device, concrete of grade not lower than M100 is used. The volume of this monolith is calculated quite simply - just multiply the length, width and height of the slab.

Pouring a solution of cement and sand with the addition of large fractions for monolithic slab produced to a height of at least 100 mm. Thus, for a slab with a thickness of 100 mm, the following volumes of concrete are obtained:

• for a house 10x8 - 8 m 3;
• for a house 9x9 - 8.1 m 3;
• for a house 18x8 - 14.4 m 3.

This calculation is suitable for completely flat slabs, but in order to give the base higher strength characteristics, additional stiffeners are often arranged in the form of trapezoidal longitudinal beams. Therefore, the correct calculation of the slab foundation must also contain the volume of pouring the stiffeners.

To the already obtained volume of the plate, it is necessary to add the volume of stiffeners, for which the trapezoid area formula is used. Volume slab foundation with stiffeners are found as follows:

1. Calculate the volume of your plate: V=h*b*l.
2. Find the area of ​​the trapezoid: S=h1*(a+c)/2, where h1 is the height of the edge of the trapezoid, and and c are the lengths of the bases of the trapezoid.
3. Find the volume of the stiffener and multiply by the number of ribs: V1=S*l*n, where n is the number of stiffeners.
4. The resulting volumes are added up and the total volume of concrete required is obtained: Vtot=V+V1.

Typically, the reinforcement is located at the bottom of the base with a step of 3000 mm. They can be performed as exclusively longitudinal amplifiers, and with intersection, forming squares. Usually the ratio of the wide part of the trapezium of the stiffener refers to the narrow part pointing down as 1.5:1. To calculate the slab foundation, they also provide for volume adjustment with an error factor of 2%.

Columnar

This type of foundation is a kind of pile field, only the supporting pillars are not clogged with a pile driver, but are poured into prepared pits. The columnar foundation allows you to get a reliable foundation with minimal material consumption. Pillars can have a round and square section, they are placed along the perimeter of the building site and at the junction of the walls.

The depth of the columnar foundation usually exceeds the freezing depth for a given area, and the ground part has a height of 400-500 mm. The building structure can be installed directly on the supporting pillars, but most often a grillage is installed around the perimeter, which connects the pillars into a single whole.

To calculate the volume of concrete required for pouring a column foundation, you need to know the length of the column, its cross-sectional area and the number of columns. If a grillage is provided, its linear dimensions will be required, the calculation of the grillage volume is carried out in the same way as in the version with a strip foundation.

V=a*b*l*n, where a and b are the sides of the section of the column, l is the length of the column, n is the number of columns in the foundation.

To calculate the volume of concrete for pouring pillars with a circular cross section, you need a formula for finding the area of ​​a circle: S=3.14*R*R, where R is the radius. We get the formula for calculating the volume of columns with a circular cross section:

To obtain the total volume of concrete required for pouring the pillars and the grillage, it is necessary to add up the already obtained indicators, not forgetting the error factor of 2%.
