Calculate adult body mass index from height and weight. Switch between metric and imperial units and see the standard BMI category.
BMI divides weight in kilograms by height in meters squared. It is a quick screening measure for adults, not a diagnosis. Muscle mass, pregnancy, age, ethnicity, and other health factors affect how useful the number is, so discuss personal concerns with a qualified health professional.
For metric inputs, the calculation divides weight in kilograms by height in meters squared.
Metric BMI is weight in kilograms divided by height in meters squared. Imperial BMI is weight in pounds divided by height in inches squared, multiplied by 703.
The standard adult healthy-weight category is 18.5 to 24.9, though BMI has important limitations.
No. BMI is only one screening measure and does not replace professional medical assessment.
