Body Mass Index using the standard WHO formula.
Body Mass Index (BMI) is a screening tool that estimates whether a person has a healthy weight for their height. It is calculated by dividing weight in kilograms by height in meters squared (kg/m²). While BMI is widely used, it has limitations — it does not account for muscle mass, bone density, or fat distribution. Athletes often have high BMIs despite low body fat.
BMI is best used as one data point among many when assessing overall health.
