The easiest way is with a BMI calculator or chart. You first need to know your exact measured weight and height. You can use metric or US measurements on most charts. These are available at different sites online. Good calculators (for adults and children) are available at the US Centers for Disease Control and Prevention (CDC) website. See the related question in the related questions section for more information on finding BMI charts and calculators.
What is BMI? From the CDC:
"Body Mass Index (BMI) is a number calculated from a person's weight and height. BMI provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems."
As an alternative, you can mathematically calculate this yourself in various ways. Here are some methods provided by Answers.com contributors:
Get your height in metres.
Divide this by your weight in kilograms.
Divide your answer by your weight again.
This will give you your BMI.
take your weight, multiply by .45 then take your height in inches and multiply it by .025 then square the result. divide the product of your weight by the product of your height and youll get a number.
ex: weight: 100 lbs height: 67 inches.
100x.45= 45 and 67x.025=1.675 1.675x1.675=2.806
45 divided by 2.806= 16.037 which rounds to a BMI of 16.
The calculation for BMI is weight in kilograms divided by height in meters squared.
kg/(Meters^2)
or you can just use a free calculator.
Use an online calculator or if not, these sums:
For Imperial
BMI = ( Weight in Pounds / ( Height in inches x Height in inches ) ) x 703
BMI = ( Weight in Kilograms / ( Height in Meters x Height in Meters ) )
BMI=weight in kilograms/(height in meters)2

How much weight do you have to lose if your bmi is 40.2 and you want your bmi to get down to 28.0?
To determine how much weight you need to lose to achieve a BMI of 28.0, you first need to know your height. BMI is calculated using the formula: BMI = weight (kg) / (height (m))^2. Once you have your height, you can rearrange the formula to find the target weight for a BMI of 28.0, then subtract your current weight (calculated from your BMI of 40.2) to find the weight loss required.
