NEiA Adult BMI Calculator

Body Mass Index (BMI) Calculator

BMI is a calculated measure of a person's body weight (in kilograms) divided by the square of their height (in meters). BMI = weight (kg) / height (m)²

BMI measures weight relative to height. This calculator is specifically designed for adults 20 years and older.

BMI does not distinguish between fat, muscle, and bone mass. These all influence a person's weight. BMI does not indicate what types of fat people have. BMI also does not indicate where in the body that people carry fat.
