Acerca de Body Fat Calculator
The US Navy circumference method estimates body fat from simple tape measurements — neck, waist (plus hips for women) and height — and has tracked within a few percent of lab methods for decades. Enter your measurements and this calculator returns your estimated body fat percentage, your fitness category, and your estimated lean body mass. Measurements are most reliable first thing in the morning, with the tape snug but not compressing skin.
