Calculate your BMI
Body mass index, or BMI, relates weight to height. Use this adult calculator as a starting point for a conversation about your health, not as a diagnosis or a test of surgical eligibility.
How the calculation works
BMI is weight in kilograms divided by height in meters squared. With pounds and total inches, the approximate formula is weight divided by height squared, multiplied by 703. Use the units shown by the calculator and check your entries.
Understand the limits of the number
The practice’s original BMI page describes the result as approximate and a rough guide. BMI uses height and weight; it does not include your medical history, symptoms or goals. A clinician needs more than this number to discuss your care.
This tool is for adult information. Ask a clinician about interpreting growth measurements for children and teenagers.
