About BMI Calculator
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 metres squared.
BMI Categories
- Underweight: BMI less than 18.5
- Normal weight: BMI between 18.5 and 24.9
- Overweight: BMI between 25 and 29.9
- Obese: BMI of 30 or greater
Limitations
While BMI is a useful screening tool, it does not diagnose body fatness or health. It does not account for muscle mass, bone density, or overall body composition. Athletes with high muscle mass may have a high BMI but not be overweight.
