A body mass index (BMI) formula is a mathematical equation that calculates a person’s body fat based on their height and weight. It is commonly used to screen for weight-related health problems such as obesity and malnutrition.
BMI is a useful tool for healthcare professionals and individuals alike to assess their weight status and make informed decisions about their health. It was developed in the 19th century by Belgian mathematician and statistician Adolphe Quetelet.
