Body Fat Calculator

The Body Fat Calculator can be used to estimate your total body fat based on specific measurements. Use the "Metric Units" tab if you are more comfortable with the International System of Units (SI). To get the best results, measure to the nearest 1/4 inch (0.5 cm). This calculation is based on the U.S. Navy method, but also includes the calculation of body fat percentage using the BMI method (both of which are outlined below).

Body Fat, Overweight, and Obesity - The scientific term for body fat is "adipose tissue." Its primary purpose is to store lipids from which the body creates energy. Body fat includes essential body fat and storage body fat.

Measuring Body Fat Percentage - The calculator uses equations developed at the Naval Health Research Center. For more accurate measurements of body fat, the use of instruments such as bioelectric impedance analysis or hydrostatic density testing is necessary.
