BMI Calculator
What is BMI?
Body Mass Index (BMI) is an approximate measure of
body composition based on a person's weight and height.
It is worked out using a formula that
uses your height and weight to calculate a
number. This number gives an approximate indication of
whether you are a healthy weight or if you are at risk of
being under or over weight.
