What is BMI? Body Mass Index (BMI) is a foundational health metric used worldwide to assess body weight relative to height. It is defined as a person's weight in kilograms divided by the square of their height in meters ($kg/m^2$). BMI provides a reliable indicator of body fatness for most people and is the primary screening tool for weight-related health risks.
