What Is BMI?

BMI is a measurement that estimates body fat based on height and weight. It is commonly used as a general health screening tool.

Metric: BMI = Weight (kg) ÷ Height² (m²)
Imperial: BMI = (Weight (lbs) × 703) ÷ Height² (inches²)

Healthy Weight Range Formula

Minimum Healthy Weight = 18.5 × Height² (m²)
Maximum Healthy Weight = 24.9 × Height² (m²)
