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.
