What Is the Body Adiposity Index (BAI) ?

The Body Adiposity Index (BAI) is a mathematical method which is used to estimate the body fat percentage by using only two measurements: 1.hip circumference and 2.height. It was an alternative to the Body Mass Index (BMI), which uses weight and height but doesn’t directly account for fat distribution.

BAI Formula:

BAI=(Height in meters1.5Hip Circumference in cm​)−18

In contrast to BMI, which may misrepresent muscular or athletic individuals, the BAI is intended to more accurately reflect body adiposity, particularly in populations that may not have access to bodyweight scales.

How to Use BAI Calculator ?

To use our Body Adiposity Index Calculator:

1. Measure your accurate hip circumference in imperial or metric units.
2. Measure your accurate height in your available units of imperial or metric.
3. Input your both values of hip circumference and height into the above Body Adiposity Index Calculator.
4. Click on “Calculate” button to get your estimated body fat percentage.
