# BMI Calculator

The BMI calculation was originally known as the Quetelet index as it was initially developed around 1830 by the Belgian Adolphe Quetelet. This valuable formula is used worldwide and is generally widely accepted as a fairly accurate measurement of identifying weight problems. The result of the BMI calculator generally groups each individual into one of the four following categories: underweight, normal, overweight, or obese.

In addition to using our BMI calculator at the bottom of this page, you might want to try calculating your BMI yourself. The formula to determine your own body mass index can be seen in the box below.
