About the BMI Calculator
Body Mass Index compares your weight with your height. This BMI calculator accepts kilograms and centimetres or pounds, feet and inches, and shows the adult WHO category and the weight range that corresponds to a BMI of 18.5 to 24.9 at your height.
How to use it
- Choose metric or imperial units.
- Enter your weight and height.
- Read your BMI, the category and the healthy weight range.
Frequently asked questions
- Is BMI a diagnosis?
- No. It is a screening figure and ignores muscle mass, age and body build. Ask a health professional for personal advice.
- Is it suitable for children?
- No. Children and teenagers use age-specific growth charts, so this adult calculator is not appropriate.
