Understanding BMI
What is BMI?
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in metres squared.
BMI is a useful measure of overweight and obesity. It is calculated the same way for both adults and children.
