Your body mass average, also known as your body mass index, is a measurement of your body fat based on your weight and height. It is only an approximation, but it is an easy preliminary way to see if your amount of body fat is proportionate to your height and weight. From the result, you can decide whether you need to gain or lose weight, or whether you need to maintain it.
Step 1
Measure your height in inches using the yardstick and record the information.
Step 2
Weigh yourself to find out your weight in pounds and record the information.
Step 3
Multiply your height in inches by itself. For example, if you are 65 in. tall, multiply 65 by 65. Your result would be 4,225.
Step 4
Divide your weight in pounds by the number you got in Step 3. For example if your weight is 150 lbs. and your height is 65 in., your result will be approximately 0.036.
Step 5
Multiply your result from Step 4 by 703. Using the previous example, your result would be 24.96.
Step 6
Compare your result with the standard weight status categories associated with adult body mass index ranges. Below 18.5 is considered underweight; between 18.5 to 24.9 is normal; between 25.0 and 29.9 is overweight; and above 30.0 is considered obese.
