Formula and method
Recorded WHtR = recorded waist in inches ÷ recorded height in inches, truncated to three decimal places. Army Directive 2026-13 uses a threshold strictly below 0.550.
Worked example
A recorded waist of 35 inches and height of 70 inches yield 0.500. A ratio of 0.5498 is recorded as 0.549, not rounded to 0.550.
