Body Mass Index (BMI) Calculator

Body mass index (BMI) is a measurement of body fat based on height and weight that applies to adult men and women. Identifying your estimated BMI helps providers understand your risk for weight-related health conditions and determine if you are a candidate for weight loss surgery. BMI can be measured through a simple formula that can be used in calculators — like the one provided below.
