Body Mass Index Calculator

BMI Calculator

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, children, and the elderly.

BMI = weight in kilograms / 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.
