What formula is used to calculate BMI?
BMI = (

Weight (lbs.)


Height (in.) x Height (in.)


) x 703

For example, if an adult weighs 190 pounds and is 5 feet 10 inches tall, he has a BMI of 27.
How did we do it? First, convert his height to inches only. 5 feet 10 inches is 70 inches. Multiply 70 times 70, which
equals 4900. Divide his weight in pounds, 190, by 4900 which equals 0.039. Multiply 0.039 by 703 which equals 26.714
(which we round up to 27).
The BMI formula is pretty easy to calculate (and even memorize!) once you try it a few times.
