BAI stands for Body Adiposity Index which calculates body fat.

BAI | Body Adiposity Index Calculator

Body Adiposity Index or simply BAI is the calculation of body fat in adults. Unlike BMI, BAI doesn’t need weight to estimate fat, rather it uses the hips size to calculate the body fat. This index is calculated by dividing the hip circumference by one and a half of their height in meters and subtracting them all to 18.

BAI is different to both males and females. For a male of age 20 to 39, 8% to 21% is the healthy fat level. In contrast, for a female of age 20 to 39, 21% to 33% is healthier.
