What the current Army standard calculates
Quick answer: the current Army calculation is waist circumference รท height. A recorded WHtR below 0.550 meets the standard; 0.550 does not. Digits after the third decimal place are discarded rather than rounded.
Recorded WHtR = truncate(WHtR, 3 decimals)
Meets standard when recorded WHtR < 0.550
Why there is no body-fat percentage: โArmy Body Fat Calculatorโ remains a common search phrase, but Army Directive 2026-13 rescinded the earlier circumference-based body-fat assessments. WHtR is now the sole authorized ABCP standard. For a general, non-Army body-fat estimate, use the separate BMI vs Body Fat Calculator.
How to use the calculator
- Choose imperial or metric. Official Army recording uses inches. For a personal estimate, centimetres produce the same ratio when both inputs use centimetres.
- Enter standing height. Measure without shoes and keep the body upright.
- Measure the waist at the navel. Keep the flexible tape level and record the measurement without mixing units.
- Review the recorded result. The calculator shows the raw division, the official-style truncated value, the 0.550 boundary waist for the entered height, and the distance from that boundary.
