BMI STANDARD INDEX FOR DIFFERENT GENDER
- The BMI (Body Mass Index) is defined as the body weight divided by the square of the body height, and is universally expressed in units of kg/m ^2 , resulting from weight in kilograms and height in metres.
$$ \mathrm{BMI} = \frac {\mathrm{w}}{\mathrm{h} ^ {2}} $$
w= weight; unit: kilogram
h= height; unit: metre
| Gender\BMI | Under weight | Normal weight Over weight Obese | |
| Male <20 20-25 26-30 >31 | |||
| Female <19 19-24 25-29 >30 | |||
- Since BMI does not consider body fat content and other body composition ratios, the BMI range is only a reference based on body weight & height.
