Body Adiposity Index (BAI)
This calculator estimates your Body Adiposity Index (BAI), a measurement of body fat percentage based on hip circumference and height. Unlike BMI, BAI doesn't require weight, making it a practical tool for evaluating body composition when scales aren't available.

Body Adiposity Index Formula
$$\text{BAI} = \left( \frac{HC}{HM^{1.5}} \right) – 18$$
Where:
– $$HC$$ = Hip Circumference (cm)
– $$HM$$ = Height (m)
The Body Adiposity Index (BAI) is used to estimate body fat percentage without needing to know your weight. It is particularly useful in field conditions or home assessments. BAI values differ by gender:
For Men:
- < 8% — Underfat
- 8–21% — Healthy
- 22–25% — Overweight
- > 25% — Obese
For Women:
- < 21% — Underfat
- 21–33% — Healthy
- 34–39% — Overweight
- > 39% — Obese
