A body mass index (BMI) formula is a tool used to calculate a person’s weight status based on their height and weight. It is a measure of body fat based on height and weight that applies to adult men and women.
BMI is an important tool for assessing health risks related to weight. It can help individuals determine if they are underweight, overweight, or obese. Historically, BMI was developed in the 19th century by Adolphe Quetelet, a Belgian statistician.
