It is necessary to know how overweight and obesity are defined and measured in scientific terms in order to do something about it.

An introduction to these things helps us understand and find our place in the chances for obesity. Calculating your chances for obesity may take a lot of patience. It is good though that our helpful health providers have devised a way for patients to determine their weight condition easily. An obesity calculator makes the process of weight measurement comprehensible and convenient to use.

The obesity calculator doesn't actually need a special calculating device in order to use. There is a lot of free obesity calculator software in the internet, available usually in health and wellness web sites. Just a few clicks and you got your BMI. But did you know that you can compute for your BMI on your own?

The body mass index or the BMI obesity calculator is a special formula designed to measure the amount of body fat in a person's body. Since not all overweight people are fat people (for example body-builders), being informed of your exact BMI and the related changes in your body allows you to know as early if you are obese. And if you're not, wouldn't it feel good to know you're not obese even it seems you are? Even thin people also get the advantage of knowing the balance between their lean muscles and fats. The method is fairly easy.

The BMI calculates based on the standard relationship between height and weight. Though it doesn't measure the exact percentage of fat in your body, it does measure the (right) proportion of your fat and muscles. And since it is not gender-specific and effective as well as easy to use, it is the choice-measurement used by most obesity researchers and other health professionals.

Though you don't need to be an expert at all. You're already on your way to having your obesity calculator once you know your math. The BMI is computed by dividing a person's weight (in kilograms) by his height (in meters) squared. In figures: weight (kg) / height squared. If you want to use pounds and inches, just multiply your weight (lbs.) by 700, then divide the result by your height (in.), and then divide that again by your height in inches. A BMI that is less than 18.5 is considered underweight. A BMI of 18.5-24.9 is considered normal-weight. A BMI of 25-29.9 is considered overweight.

In essence, you will be able to have a personal conviction with your weight - health once you become knowledgeable of what goes on with of your BMI as you follow through with its development.
