Calculate Body Mass Index in metric or imperial units with WHO classification.
About this Calculator
Body Mass Index (BMI) is a widely used screening tool for body weight categories. Enter your height and weight in metric (cm/kg) or imperial (ft/in/lbs) units to calculate your BMI and see where you fall in the WHO classification: underweight, normal weight, overweight, or obese. While BMI has limitations — it doesn't account for muscle mass or body fat distribution — it remains a useful population-level health indicator and starting point for health discussions.
