Body Mass Index (BMI)
Body Mass Index or BMI is an index as the name indicates. Therefore it has no units and is a pure number. The BMI of a person is calculated as the weight in kgs divided by the square of the height in meters. While the BMI for an adult should ideally be between 21 and 25, the BMI of children is usually much lower. The BMI for different ages and sexes can be downloaded from the Resources Page in the form of a table (BMI Table)
