USING THIS TOOL

How Adult BMI Calculator helps

Choose centimetres/kilograms or inches/pounds. Receive your BMI and a general adult screening category.

Method and assumptions

BMI = mass in kilograms ÷ (height in metres)². It cannot distinguish muscle and fat.

Example

At 70 kg and 1.75 m, BMI is about 22.9. Adult ranges are general screening information.

Know the limits

Check your inputs and verify important financial, health, legal, educational or property decisions using the relevant professional or official source. Results depend on stated assumptions.
