calculate target waist size from target bodyfat (and height & neck)

Gender Male
Female
Units Inches
Centimeters
Height
Neck
Target Bodyfat % (optional)

This will generate a table of bodyfat percentages and your corresponding abdomen measurements for men, or waist + hip sizes for women.

It uses the U.S. Military (DoD) bodyfat formulas.

Neck measurements are assumed constant. If this assumption distresses you, enter your neck measurement as 0, and the resutls for men will be abdomen - neck, and for women will be waist + hip - neck.

The tables used for these calculations which are based on the same formulas only list male bodyfat percentages from 9% to 37%, and female bodyfat percentages from 19% to 47%. These may be reasonable ranges within to expect some semblance of accuracy.
