How It Works
The Formula
US Navy: 495 ÷ (1.0324 − 0.19077×log₁₀(waist−neck) + 0.15456×log₁₀(height)) − 450
Circumference measurements in inches
Worked Example
Waist 34" · Neck 15" · Height 70" (male)
- 1495 ÷ (1.0324 − 0.19077×log₁₀(19) + 0.15456×log₁₀(70)) − 450
- 2≈ 495 ÷ 1.0290 − 450
Result: ≈ 16.9% body fat
