A body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. The imperial formula for calculating BMI is weight in pounds divided by the square of height in inches, multiplied by a conversion factor of 703.
BMI is a widely used metric for assessing weight status and is categorized as underweight, normal weight, overweight, or obese. It helps healthcare professionals determine a person’s risk of weight-related health problems and provides valuable insights into weight management and tailored health interventions.
