It is used for both men and women, age 18 or older. This is the World Health Organization's (WHO) recommended body weight based on BMI values for adults. Refer to the table below to see the different categories based on BMI that are used by the calculator. Being overweight or underweight can have significant health effects, so while BMI is an imperfect measure of healthy body weight, it is a useful indicator of whether any additional testing or action is required. These ranges of BMI vary based on factors such as region and age, and are sometimes further divided into subcategories such as severely underweight or very severely obese. Specifically, the value obtained from the calculation of BMI is used to categorize whether a person is underweight, normal weight, overweight, or obese depending on what range the value falls between. It is widely used as a general indicator of whether a person has a healthy body weight for their height. Note that the calculator also computes the Ponderal Index in addition to BMI, both of which are discussed below in detail.īMI is a measurement of a person's leanness or corpulence based on their height and weight, and is intended to quantify tissue mass. Use the "Metric Units" tab for the International System of Units or the "Other Units" tab to convert units into either US or metric units. While the BMI can contribute to an assessment of an individual's weight and health status, it is to be noted that it is not a direct measure of either weight or health.The Body Mass Index (BMI) Calculator can be used to calculate BMI value and corresponding weight status while taking age into consideration. "standard BMI has survived as a robust, useful and surprisingly accurate measure of fatness in A recent article in the International Journal of Epidemiology noted, the Today, the BMI is widely used as an indirect measure of the amount of fatness, since, despite its shortcomings, it is a simple and relatively reliable tool. Quetelet found that the height-weight of a population as measured using the Quetelet Index fits the Gaussian curve whereas a simple height to weight ratio does not. Quetelet did not intend that the Quetelet Index be used to assess the obesity or health status of individuals but was interested in the statistics of various human attributes in populations. One hundred and forty years later, the American physiologist Ancel Keys coined the term Body Mass Index by which we know the Quetelet Index today. The index was originally known as the Quetelet Index and was first devised by the Belgian polymath and founding social scientist, Adolphe Quetelet in 1832. Metric: Enter your weight in kilograms (kg) and height in centimeters (cm). Standard: Enter your weight in pounds (lb) and height in feet (ft) and inches (in).

How to Use the Body Mass Index Calculator
The resulting value is then classified as underweight, normal, overweight, or obese by reference to ranges issued by an appropriate health organization.Ī BMI calculator is a useful tool to determine an individual's BMI value since the calculator automatically computes the BMI from a user's weight and height. To calculate BMI using pounds and inches,ĭivided by their height in inches (in) squared and the result is
(the original formula uses metric values). In the US, it is common to adjust the formula to work with standard weight and height measures
This calculator is forīMI is an abbreviation of Body Mass Index.Ī BMI value is obtained by dividing an individual's weight (kg) by BMI is anĮstimate of body fat derived from an individual's height and weight. Our BMI calculator uses your weight and height to calculate your body mass index (BMI).
