Body Adiposity Index Calculator


15

The Body Adiposity Index Calculator determines the Body Adiposity Index (BAI) in your body. The BAI is used to determine the body mass percentage that comprises the fat as against the mass which is fat-free. The fat-free mass, as the name carries, encompasses everything in the body except the fat. It is essential to keep in mind that although most people feel that their body adiposity index may be too high, it can also be detrimental to have a body adiposity index that is too low. A body adiposity index classification table (displayed in the section) provides a guideline for what body adiposity ranges are considered to be underweight, healthy, overweight, and obese. You need to feed in your height, age group, gender, and hip circumference to find the Body Adiposity Index (BAI) Percentage.

How is Body Adiposity Index (BAI) Calculated?


The following equation is used to provide you your body adiposity index.

BAI = ( Hip Circumference in centimeters / (Height in meters)1.5 ) - 18

To get the result, the height in meters is first powered to 1.5 and the hip circumference in centimeters is divided by the result and then 18 is subtracted from it. Thus, the BAI has been derived.
