US Army method (AR 600-9): men BF% = 86.010×log10(abdomen−neck) − 70.041×log10(height) + 36.76; women: 163.205×log10(waist+hip−neck) − 97.684×log10(height) − 78.387. Standards are age-based per AR 600-9 (2019). Results are estimates — official APFT tape tests must be administered by qualified personnel. Not an official military assessment tool.
