Body Mass Index (BMI) estimates body fat based on weight and height. You can enter either metric measurements (kilograms and centimeters) or U.S. measurements (pounds and inches). The calculator converts U.S. units to metric before computing BMI as weight in kilograms divided by height in meters squared.
Basal Metabolic Rate is the number of calories your body uses at rest. It depends on your age, gender, weight and height. This calculator accepts both metric (kg/cm) and U.S. (lb/in) inputs and converts U.S. measurements to metric before using the Mifflin–St Jeor equation.
This calculator uses the U.S. Navy method, which estimates body fat percentage based on neck, waist, hip (for women) and height measurements. You can enter measurements in centimeters or inches; any U.S. measurements are converted to centimeters internally.
