Body Adiposity Index Calculator

Hip Circumference

Note: Hip circumference measurements should be made by placing tape measure around the hips so that it passes over the greatest protrustion of the buttocks as viewed from the side.

Height

Body adiposity index classification ranges for men and women, as outlined by Gallagher et al., are shown in the table below.

## Equations

The equations used by this calculator to determine your body adiposity index are shown below.

• BAI = HC / (HM)1.5

where

BAI = Body Adiposity Index
HM = Height in Metres
HC = Hip Circumference in Centimetres
