BMI, which stands for body mass index, is your weight in kg divided by your height in metres squared.
Example. Say you are 1.65 m tall and your weight is 72. Multiply 1.65 by itself to get 2.72, and 72 divided by 2.72 gives a BMI of 26.4.
The catch. BMI mixes up fat and muscle, so it misleads for athletes, for people over 65 and in pregnancy.
