Calculate your BMI

Calculate Your Body Mass Index.

Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. BMI is a person’s weight in kilograms (kg) divided by his or her height in meters squared. The National Institutes of Health (NIH) now defines normal weight, overweight, and obesity according to BMI rather than the traditional height/weight charts.

BMI Categories:

Underweight = <18.5
Normal weight = 18.5–24.9
Overweight = 25–29.9
Obesity = BMI of 30 or greater
