Body mass index (BMI) is a measure of body fat based on height and weight. It is used to assess the risk of obesity-related health problems. To calculate BMI using pounds and inches, divide weight in pounds by the square of height in inches and multiply by 703: BMI = (weight in pounds / (height in inches)^2) x 703
BMI is a valuable tool for healthcare professionals and individuals to assess and track weight status. It can help identify individuals who are at risk for weight-related health problems, monitor progress in weight management programs, and evaluate the effectiveness of interventions. The concept of BMI was first developed in the early 19th century by Adolphe Quetelet, a Belgian mathematician, astronomer, and statistician.
