What is Body Mass Index (BMI)?

The Body Mass Index (BMI) is a tool that can be used to tell how healthy a person's weight is. You can use the BMI to find out if you're a healthy weight for your height.

If you know your height and weight, you can work out which weight range you're in using the simple steps outlined below.

  • Take your weight in kilograms (kg) and divide it by your height in metres (m).
  • Then divide the result by your height in metres (m) again.

For example, if you weigh 70kg, and you're 1.75m tall, your BMI would be 22.9 (70/1.75 = 40 and 40/1.75 = 22.9).
