What is BMI?

Body Mass Index (BMI) is a measure of a person's weight in relation to height. To calculate your BMI, multiply your weight in pounds and divide that by the square of your height in inches; being considered overweight is having a BMI greater than 25; to be considered obese is to have a BMI greater than 30).

The mathematical formula used to calculate BMI is:
bmi = weight in kilograms divided by height in meters, squared

The goal for most people is a BMI that’s between 19 and 24.9.
A BMI of between 25 and 29.9 is considered overweight
AA BMI of 30 or greater is considered obese.

 

How The Body Mass Index (BMI) Calculator Works

Body Mass Index (BMI) is a general indicator of whether or not you are maintaining a healthy weight based on the ratio of your weight to your height. It’s an imperfect scale as it doesn't account for differences in body types. For example, a 5 foot 9 inch bodybuilder who weighs 215 pounds and has a 6% body fat would be labeled obese. And there is already a new scale just for people from Southeast Asia where the ranges are lowered.

While it can be a good indicator of the healthiness of your weight if you fall within certain statistical norms that were used to develop it, it should be taken with a significant grain of salt and should not be used as a substitute for a professional evaluation of your health by a doctor.
