Understanding BMI

Body Mass Index (BMI) is calculated as weight divided by height squared. In metric: BMI = kg / m^2. In imperial: BMI = (lb / in^2) x 703. BMI is a screening tool, not a diagnostic measure. It does not distinguish between muscle and fat mass. Consult a healthcare professional for personalized advice. Built by Groundwork Analytics.
