Enter your weight and height to calculate your Body Mass Index. We will show you your BMI, your category, and — importantly — what BMI can and cannot tell you about your health.
How BMI Is Calculated
In metric units: BMI = weight (kg) ÷ height (m)². A person who weighs 70kg and stands 1.75m tall has a BMI of 70 ÷ (1.75 × 1.75) = 22.9.
In imperial units: BMI = (weight (lbs) ÷ height (inches)²) × 703. The 703 factor converts the result from the imperial measurement system to the standard BMI scale.
