Body Fat % from Girth Measurements
There are formula from the US Department of Defense to compute body-fat percentage using
girth measurements and height. There are different formulas for males and females. The males
require girth measures of the neck and abdominal girth. The females require girths of the neck,
waist and hip.
This is the formula (Hodgdon and Beckett, 1984) that was taken from the Navy website, and is
seen elsewhere on the internet. Note, all measurements are in inches (measured to the nearest 1/4
inch), including height.
males: % body fat = 86.010 x (abdomen - neck) - 70.041 x (height) + 36.76
females: % body fat = 163.205 x (waist + hip - neck) - 97.684 x (height) - 78.387
