The meaning of BMI's

The Body Mass Index (BMI) is a guide to whether someone is underweight, normal weight or overweight. You can calculate the BMI using this formula:

BMI = mass in kg ÷ (height in m)2

Question: What is the BMI of a 1.7 metre-tall person with a body mass of 60kg?

Answer:  BMI = 60 ÷ (1.7)2 = 20.8

In this example, the person would be at the ideal weight for their height.
