How this calculator works

Uses the US Navy circumference equations (Hodgdon & Beckett, 1984): men %BF = 86.010·log10(waist − neck) − 70.041·log10(height) + 36.76; women %BF = 163.205·log10(waist + hip − neck) − 97.684·log10(height) − 78.387 (inches). Categories follow the American Council on Exercise.
