BMI Calculator

A BMI calculator is a tool used to determine a person's body mass index. This does not measure body fat directly, but correlates quite closely to direct measures of body fat. In order to gauge a person's body mass index using a BMI calculator, the only information you need is his or her height and weight.

What Is a BMI Calculator?

Research on obesity has shown that a measurement called body mass index, or BMI for short, can be used to assess a person's level of body fat based on his or her height and weight. BMI does not measure body fat directly, but it correlates closely to direct measures of body fat.
 
The BMI calculator is used to determine the body mass index of a person 20 years of age or older.
 
For adults, BMI is interpreted through categories that do not take factors such as sex or age into account.
