Estimate body fat percentage using the official US Army circumference method.
The Army method uses the same waist/neck/height (and hip, for women) measurements as the Navy method but with different formula coefficients, since it was calibrated against a different reference population and standard. Results are usually close to, but not identical to, the Navy method.
