Estimate your body fat percentage using the US Navy circumference method from waist, neck, and height measurements.
Body fat percentage is the proportion of your total body weight that is made up of fat, as opposed to muscle, bone, and other lean tissue. It is a more meaningful health indicator than weight alone.
Calcify estimates body fat percentage using the US Navy circumference method, which relies on waist, neck, and height measurements (plus hip measurement for females) rather than expensive equipment.
