US Navy Method
The U.S. Navy body fat formula uses measurements of height, neck, waist, and hip (for females) circumference to estimate body fat percentage.
For males: %BodyFat = 495/(1.0324 – 0.19077*log10(waist – neck) + 0.15456*log10(height)) – 450
For females: %BodyFat = 495/(1.29579 – 0.35004*log10(waist + hip – neck) + 0.22100*log10(height)) – 450
