Definition: BMI is an abbreviation for body mass index, and is calculated with a child's height and weight using a simple BMI formula, a BMI calculator, or by looking it up on a BMI wheel or BMI tables.

Although it doesn't measure body fat, BMI can be used to determine if a child is overweight, underweight, or at a healthy weight.

Pronunciation: B.M.I.
