### How do you find out the percentage?

How Do we Calculate Percentage? Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage is: (value/total value)×100%.

The BMI is generally used as a means of correlation between groups related by general mass and can serve as a vague means of estimating adiposity. The duality of the BMI is that, while it is easy to use as a general calculation, it is limited as to how accurate and pertinent the data obtained from it can be. Generally, the index is suitable for recognizing trends within sedentary or overweight individuals because there is a smaller margin of error. The BMI has been used by the WHO as the standard for recording obesity statistics since the early 1980s. The BMI is expressed in kg/m2, resulting from mass in kilograms and height in metres. If pounds and inches are used, a conversion factor of 703 (kg/m2)/(lb/in2) is applied. When the term BMI is used informally, the units are usually omitted.

## What are the limitations of BMI?

Nevertheless, due to its simplicity, it has come to be widely used for preliminary diagnoses. Additional metrics, such as waist circumference, can be more useful. Body mass index Chart showing body mass index for a range of heights and weights in both metric and imperial. Colours indicate BMI categories defined by the World Health Organization; underweight, normal weight, overweight, moderately obese, severely obese and very severely obese. Even though the BMI chart can be inaccurate for certain people, healthcare providers still use it because it’s the quickest tool for assessing a person’s estimated body fat amount.

It’s important to remember that you could have any of the above health conditions without having a high BMI. Similarly, you could have a high BMI without having any of these conditions. Genetics and other factors, such as smoking cigarettes, play a large role in the development of these conditions. This measure does not take into account your age, race, sex, or fitness level. Consider BMI for what it is—an estimate, not a measurement, and just one piece of information that can help paint the picture of your overall health. Your healthcare provider can help you better understand how your BMI fits in.

## Metric Method

It can help assess risk factors for certain health conditions. The BMI is not always an accurate representation of body fatness. However, on an individual level, BMI can be less accurate, and it is best used in conjunction with other data (e.g., body composition tests) in the full assessment of an individual’s weight status.

### What is the symbol for average?

The average is basically the mean of the values which are represented by x̄. It is also denoted by the symbol 'μ'.

The optimal BMI was found to be in the range of 22.5–25. The average BMI of athletes is 22.4 for women and 23.6 for men. Also, the growth of a child is documented against a BMI-measured growth chart.

BMI is only an estimate that cannot take body composition into account. Body mass index, or BMI, uses a simple equation to measure the relationship of your height to your weight, telling you if you have a healthy level of body fat. Although body mass index is a good measure for much of the population, it’s not infallible. In muscular body types — particularly bodybuilders or other stocky, beefy athletes — your BMI may show you as having overweight even though you’re lean and healthy.

BMI Prime, a modification of the BMI system, is the ratio of actual BMI to upper limit optimal BMI (currently defined at 25 kg/m2), i.e., the actual BMI expressed as a proportion of upper limit optimal. The ratio of actual body weight to body weight for upper limit optimal BMI (25 kg/m2) is equal to BMI Prime. BMI Prime is a dimensionless number independent of units. Individuals with BMI Prime less than 0.74 are underweight; those with between 0.74 and 1.00 have optimal weight; and those at 1.00 or greater are overweight.
