How will you calculate BMI using a BMI calculator?

Allcalculator.net's If you want to calculate your BMI, you must find your exact weight and height. Once you know your height and weight values, you can input the values in the required box. You can get the result by implementing the below steps:

  • Multiply your height by itself, i.e., (height x height)
  • Divide your weight by the answer you get on the above step by squaring the height

You can also calculate your BMI using formulas as follows:

International System of Units (SI)

BMI = weight (kg) ÷ height (m2)

Imperial system 

BMI = weight (lb) ÷ height (inches) 

Does the BMI scale work for athletic people?

BMI is not a reliable measurement for a person who has body fat and also for athletes. Some of the other methods can offer an accurate result. Body fat percentage better indicates an athlete's health and athleticism than BMI. Most women athletes should fall into the range of 12 to 22 per cent body fat, and male athletes range from 5 to 13 per cent. The reason why BMI has become the most common measurement of body fat is that it does work for the majority of people. After all, most people are not athletes.  

Does BMI be interpreted differently?

BMI is interpreted differently for teens and children even though it is calculated with the same formula. This change occurs because of changes in height and weight with age and their relation to body fatness. Obesity is a BMI at or above the 95th percentile for children and teens of the same age and sex. It means that the child's BMI is greater than the BMI of 95% of 10-year-old boys in the reference population. Based on the CDC growth charts, healthy weight status is based on BMI between the 5th and 85th percentile for children and teens.
