BMI - Body Mass Index



The BMI formula

The Body Mass Index (BMI) formula was developed by Belgium statistician Adolphe Quelet(1796-1874), and was known as the Quetelet Index. BMI is also referred to as 'body mass indicator'. BMI is an internationally used measure of obesity.

How to calculate BMI

For users who wish to manually calculate BMI we have provided a BMI formula for both imperial & metric measurements. We also offer an online BMI Calculator in imperial measurements. Body mass index calculation is very straightforward. Calculating body mass index requires only two measurements, height & weight.



You can either use the formula above, or if you prefer, use the calculator below.

The chart below is the standard BMI Cart according to the medical establishment. Your weight and BMI might place you in the category of "morbidly" obese. But since we are all happy gainers here at Gainer Web, then we don't like that word "morbid" so we prefer the word "massive" instead, because we are all cheerful and happy fatties here! There is nothing "morbid" about us! Also we love the word "obese" because it does sound kind of sassy in defiance of the social norms set by society in general.

Match your BMI on this chart to determine what your BMI means, according to the medical establishment, that is!

Since the chart above is the one used by the medical establishment, we can just ignore it and use the next chart below instead. What is considered obese by the medical establishment is merely chubby by our standards, because we are happy gainers here. So instead, use the chart below to find out where you're at by our upwardly revised and more liberalized standards.

OK! Now match your BMI on THIS CHART to determine what your BMI really means!

Now, isn't this chart much better? Instead of using the term "morbid" to describe obesity, it's much nicer to use the word "massive" instead. Also, for us happy gainers, there is no such thing as being too fat. The fatter the better! This chart is a lot more fun!

OK! Now let's see if you can break the following records.
The heaviest male on record was Jon Brower Minnoch (1941-1983) of 
Bainbridge Island, Washington. He was 6 ft 1 in tall and weighed 
over 1400 pounds, BMI 185!

The heaviest female on record was Carol Yager (1960-1994) of Flint, Michigan. She was only 5 ft 7 in tall and she weighed over 1600 pounds! BMI 251!!!
Aw! Come on guys! Can't we do better than that???
