Body mass index in metric or imperial units.
About this tool
BMI is your weight divided by your height squared. Under 18.5 is underweight, 18.5 to 24.9 is normal, 25 to 29.9 is overweight and 30 or more is obese, using the World Health Organization ranges for adults.
BMI is a general guide only. It does not measure body fat or muscle, and it is not medical advice. Talk to a doctor about your health.
