Body Mass Index Calculator
Approximate how much body fat you have by simply entering your height and weight.
Entering Your Information
The Body Mass Index Calculator can be used as a general gauge of how appropriate your body weight is for your height. By entering your current height and weight, you can assess if you are underweight, overweight, or just right.
The BMI Calculator is based on data taken from middle-aged men and women. It may not be accurate for pregnant or nursing women, competitive athletes, and the elderly. The normal ranges for BMI in children are entirely different, and vary according to age and gender.
If you have used other A.D.A.M. tools, some of this information may be filled in for you.
1. Click the appropriate button to indicate if you are entering your weight in pounds or kilograms.
2. Enter your weight.
3. Click the appropriate button to indicate if you are entering your height in feet and inches or in meters and centimeters.
4. Enter your height.
5. Select your status: NONE, BODYBUILDING/ATHLETE, PREGNANT, BREASTFEEDING, or UNDER 18 years of age.
6. When you're finished, click SUBMIT to display the results.
Note: The BMI ranges used in this calculator derive from the BMI guidelines of the National Heart, Lung, and Blood Institute (NHLBI), in cooperation with the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), of the National Institutes of Health, as published in Clinical Guidelines on the Identification, Evaluation, and Treatment of Overweight and Obesity in Adults, 1998.Interpreting the Results
The BMI Calculator converts all measurements to the metric standard and then computes the Body Mass Index using the following formula:
weight in kilograms
BMI = ---------------------------------------
height in meters squared
Results:
A BMI less than 18.5 indicates that you may be underweight.
A BMI between 18.5 and 24.9 indicates that you are in a healthy weight range.
A BMI between 25 and 30 indicates that may be overweight.
A BMI over 30 indicates that you may be obese.
The BMI Calculator is not accurate for all body types. To assess if your weight is within a healthy range for your body type, contact your health-care provider.
More About This Tool
A BMI of 18.5 to 24.9 is generally considered a healthy weight for most people. Research has indicated that lower BMIs (less than 18.5) and higher BMIs (25+) are associated with increased health risks.
