About BMI

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women.

BMI is calculated by dividing weight in kilograms by height in meters squared (kg/m²).

Note: BMI is a screening tool and is not intended to diagnose disease or illness. Please consult with a healthcare professional for medical advice.

BMI Formula

Metric: BMI = weight (kg) ÷ height² (m²)

Imperial: BMI = (weight (lbs) ÷ height² (in²)) × 703
