Estimate body fat with Army measurements.
Formula: Men: BF% = 86.010 log10(abdomen−neck) − 70.041 log10(height) + 36.76; Women: BF% = 163.205 log10(waist+hip−neck) − 97.684 log10(height) − 78.387
Use the same units and measurement method expected by the calculator. Results from body measurements, activity levels, or health formulas are estimates and can vary when the underlying inputs or method changes.
Repeat the calculation with the same measurements and method, then compare the result with the displayed formula. Treat the result as an estimate where applicable.
