How It Works
BMI = weight(kg) / height(m)^2
Imperial inputs are converted to metric inside the engine before calculation.
Examples
- A person who weighs 180 lb and is 70 in tall has a BMI of about 25.8. The same formula works with kg and cm by switching the unit controls.
FAQs
Is BMI a diagnosis?
No. BMI is a screening metric and should be interpreted with age, sex, body composition, and clinical context.
Can athletes have high BMI?
Yes. Muscle mass can raise BMI even when body fat is not elevated.
