About BMI

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.

Limitations

BMI does not measure body fat directly and may not be accurate for athletes, pregnant women, elderly individuals, or certain ethnic groups. It's best used as a general screening tool.
