BMI Calculator

Calculate your Body Mass Index (BMI) using your height and weight. BMI is a common screening tool to assess whether your weight is healthy for your height.

What is BMI?

Body Mass Index (BMI) is a simple calculation using height and weight that is used to broadly categorize a person as underweight, normal weight, overweight, or obese. It's a screening tool, not a diagnostic of body fatness or health.

BMI Formula

BMI = Weight (kg) / [Height (m)]². This calculator automatically converts your height from centimeters to meters for the calculation.
