This on-line ABSI calculator takes your height and hip circumference and calculates the BAI value. Then, based on the selected ethnicity, age and gender, it will identify the Health risk classification in which the body fat percentage comes under.

- Select the unite of measurement. Either Metric (Kilogram, centimeter, etc..) or U.S.A Standard / Imperial (Pound, Inches, Feet, etc..).
- Select your Gender
- Select your Age. You can select from 10 years to 79 years.

Body Adiposity Index (BAI) is one among the attempts to identify the obesity of the human body by calculating the percentage of body fat using height and hip circumference. BAI was formulated in order to overcome the shortfalls of the widely used Body Mass Index (BMI). But according to some researched, BAI is not more accurate than BMI (see reference below).

Formula to calculate the BAI:

BAI = (Hip / Height^{1.5}) - 18

- Hip = Hip Circumference in centimeters (cm).
- Height = Height in Meters (m).
- BMI = Body Adiposity Index in % of body fat

(This body adiposity index risk classification is based on the journal "Healthy percentage body fat ranges" by Dympna Gallagher, Steven B Heymsfield,.... See reference below)
