bmi calculator

BMI was designed to be used as a pure means of listing inactive communities, with average body composition. BMI gives a simple numeric example of a person's thickness or thinness, allowing health professionals to discuss weight problems more accurately with their patients.

Adolphe Quetelet, a Belgian scientist devised the principle of the BMI between 1830 and 1850 as he developed what he called "social physics". The current term "body mass index" (BMI) for the ratio of human body weight to squared height was issued in a paper written in the July 1972 publication of the Journal of Chronic Diseases by Ancel Keys and others. In this article, Keys claimed that what he termed the BMI was "...if not fully satisfactory, at least as good as any other relative weight index as an indicator of comparative obesity".
