Body mass index (BMI) calculation is a mathematical formula that estimates body fat based on height and weight, providing a simple way to assess an individual’s weight status.
Calculating BMI is essential for healthcare professionals and individuals to identify potential health risks associated with underweight, overweight, or obesity. Its historical origins can be traced back to the 19th century, when Belgian astronomer and statistician Adolphe Quetelet developed a method for classifying body types based on height and weight.
