What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9.

How to Use This Calculator

Enter your weight and height in either metric (kilograms and centimeters) or imperial (pounds and feet/inches) units. Your BMI will be calculated automatically. The result will show which category you fall into based on the WHO standard classification.
