BMI Calculator: One Way to Assess Your Body Fat

Like body fat percentage, the BMI (Body Mass Index) is a number that is used in the medical field to classify an adult as underweight, healthy, overweight, or obese.

This BMI calculator uses the standard formula, based only on your height and weight. The formula is fairly accurate for those without a lot of muscle mass so it tends to work better for women.

Quick Facts About the Body Mass Index:

The BMI was created in the 1800s as a way to calculate body fat based on height and weight.
Many men find that the BMI overestimates body fat. This is because the actual calculation does not account for gender and muscle mass.
Many health experts agree that the BMI alone is not an adequate way to assess your body fat and risk of future health problems.
