The body mass index (BMI) is a measure of weight relative to height and is commonly used to determine if your body weight is healthy, underweight, overweight or obese. BMI is defined as the weight in kg divided by the square of the height in meters. Note that BMI calculation is age-independent and the same for both sexes i.e., The same formula is used for both adult males and females. However, for children under 18 years of age, BMI values are interpreted based on sex- and age-specific percentiles.
