The BMI is a formula that takes into consideration your height and your weight, and gives you an indication of whether you are overweight, obese, or in good shape. To calculate your BMI, multiply your weight in pounds by 703, and divide the number by your height in inches squared.
For example, let’s say you are 6 feet tall (that’s 72 inches) and weigh 200 pounds. First we multiply your weight by 703.
200 x 703 = 140,600
Next we calculate your height in inches squared, meaning we multiply the number by itself.
72 x 72 = 5,184
Now we divide the first number by the second.
140,600 divided by 5,184 = 27.1
That’s not terrible. a BMI between 25 and 30 indicates you’re overweight. Over 30 signifies obesity.
