The Navy method uses equations developed by the U.S. Naval Health Research Center to estimate body fat percentage based on height and circumference measurements.
Formula (Men): 495 / (1.0324 - 0.19077 * log10(Waist-Neck) + 0.15456 * log10(Height)) - 450
495 / (1.0324 - 0.19077 * log10(Waist-Neck) + 0.15456 * log10(Height)) - 450
Example: A male with 180cm Height, 40cm Neck, and 90cm Waist.
It is generally accurate within 3-4% for most individuals but can be less precise for elite athletes or those with high muscle mass.
Healthy ranges typically vary: 10-20% for men and 18-28% for women are often considered 'fitness' or 'healthy' levels.
