體脂率計算器
精準計算您的體脂百分比
📋 This is an estimate, not a clinical measurement. The Navy circumference method is a validated home-use formula. Individual results may differ from DEXA scans by several percentage points. Best used for tracking trends over time under consistent conditions — same method, same time of day, same measurement technique. If you have health concerns, consult a qualified healthcare provider.

Editorial Note & Sources
This calculator uses the U.S. Navy circumference method, a validated formula published in U.S. Navy instructions[1] and further validated by Potter et al. (2022) in a study of 609 Marines[2]. The Navy method is suitable for home tracking but may differ from DEXA scans by several percentage points. Results are estimates, not clinical measurements.
