In the English System, it is calculated as follows: your weight (in pounds) divided by height squared (in inches) multiplied by 703.
Male athletes with a high muscle-to-fat ratio have a BMI that is misleadingly high in comparison to their body fat proportion. As of 2014, the following are value recommendations for such individuals: A BMI of 18.5 to 25 kg/m2 may represent appropriate weight, while a BMI of less than 18.5 indicates underweight, a figure of 25 to 30 indicates overweight, and a number of 30 or more indicates obesity. BMI was created as a simple way to categorize average sedentary (physically inactive) populations with a similar body composition.
The units are generally omitted when the word BMI is used casually.īMI is a basic numeric measure of a person’s thickness or thinness that allows health practitioners to address weight issues with their patients more objectively. If pounds and inches are employed, a 703 (kg/m2)/(lb/in2) conversion factor must be used. The BMI is calculated by multiplying the weight in kilograms by the height in meters. Additional measurements, such as waist circumference, can be beneficial. Despite this, it has become frequently utilized for preliminary diagnostics due to its simplicity. BMI, according to Keys, is appropriate for population studies but not for individual evaluation. The desire for a body fat index arose in response to rising obesity rates in developed Western societies. In this work, Keys stated that the BMI was “…at least as excellent as any other relative weight index as a predictor of relative obesity, if not totally satisfactory.” Ancel Keys and colleagues invented the term “body mass index” (BMI) to describe the ratio of human body weight to squared height in a paper published in the Journal of Chronic Diseases in July 1972. The BMI can be calculated using a table or chart that shows BMI as a function of mass and height, with contour lines or colors for different BMI categories and other units of measurement (converted to metric units for the calculation).įollowing are the weight categories used to calculate BMI: BMI (kg/m) 2īetween 18, Adolphe Quetelet, a Belgian astronomer, mathematician, statistician, and sociologist, constructed what he dubbed “social physics” and devised the BMI’s foundation. The BMI is calculated by dividing the body mass by the square of the body height, and it is always expressed in kilograms per square meter (kg/m2), with mass in kilograms and height in meters. The body mass index (BMI) is a number calculated from a person’s weight and height.
