BMI Calculator

Calculate body mass index from height and weight in metric or imperial units.

How it works

BMI is weight in kilograms divided by height in metres squared. It is a screening number, not a diagnosis; it does not account for muscle mass, age or body composition. Speak to a health professional about your results.

Results are estimates for information only. They are not financial, medical or professional advice. Calculations run in your browser and your numbers are never sent to our server.
