Body Mass Index (BMI) is a widely used measurement that evaluates a person's body weight relative to their height. It helps determine whether someone is underweight, within a healthy range, overweight, or obese.
BMI is calculated using body weight and height. Although it does not measure body fat directly, it is widely used in medical screening to estimate potential health risks associated with weight.
BMI = weight (kg) / height² (m)
