Calculate your Body Mass Index (BMI) instantly and understand whether you are underweight, healthy, overweight or obese.
BMI (Body Mass Index) is a simple calculation using height and weight to estimate body fat levels.
BMI is calculated by dividing your weight in kilograms by the square of your height in meters.
BMI is a useful screening tool but does not directly measure body fat.
Athletes may have a higher BMI because of muscle mass, so BMI should be interpreted with caution.
