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.

Children and adolescents are not evaluated using these thresholds but are evaluated relative to others of the same age and gender.For example, in Singapore and Hong Kong a BMI of 23.0 is considered overweight, whereas in the United States a BMI of 25 is considered overweight.
