Open BMI CalculatorA BMI of 18.5 to 24.9 is considered healthy for most adults. However, BMI does not account for muscle mass, bone density, or body composition.
BMI = weight (kg) / height (m)^2. In imperial units: BMI = (weight in lbs * 703) / (height in inches)^2.
BMI may overestimate body fat in muscular athletes and underestimate it in elderly people. It is a screening tool, not a diagnostic measure.
