HOW TO CALCULATE YOUR BODY MASS INDEX OR BMI :D

How  how !!
BMI is your weight (in kilograms) over your height squared (in centimeters). Let’s calculate, however, using pounds and inches.
For instance, the BMI of a person who is 5’3" and weighs 125 lbs is calculated as follows:

Multiply the weight in pounds by 0.45 (the metric conversion factor) 1. 25 X 0.45 = 56.25 kg 2. Multiply the height in inches by 0.025 (the metric conversion factor) #Likethis-> 63 X 0.025 = 1.575 m 3. Square the answer from step 2 #Likethis->1.575 X 1.575 = 2.480625 4.Divide the answer from step 1 by the answer from step 3 #Likethis -> 56.25 : 2.480625 = 22.7 Thus in the box bellow you have, Voila !! The answer ! The BMI for a person who is 5’3" and weighs 125 lbs is 22.7 or practically, 23.

Metric Method

The metric formula accepts height measurements in meters and weight in kilograms. If you know your height in centimeters only, simply divide the number of centimeters by 100 convert it to meters.

For example, a person who is 183cms tall is 1.83m tall (183cm / 100 = 1.83m).

Using the metric formula is even easier than the imperial method as it's a two step process

1. Multiply your height by itself.
2. Divide your weight in kilograms by the value calculated in step 1.

The resulting number is your BMI. Compare this BMI value with the weight status table below.

Imperial (US) Method

The imperial formula accepts height measurements in inches and weight in pounds. It's popular in the US where the imperial system is mostly used. Many people know their height in feet and inches, but not in inches only.

If this applies to you, we need to convert your height into inches so we can use it in the equation. There are 12 inches in a foot, so multiply your number of feet by 12 and add them to the number of extra inches.

For example, if your height is 5 feet 10 inches, multiply 5 by 12 (which gives 60") and add them to the extra 10 inches (which gives 70").

Now we have the right measurements we can use them in the formula.

There are three simple steps for computing BMI with imperial values:

1. Multiply your weight in pounds by 703.
2. Multiply your height in inches by itself
3. Divide the figure from step 1 by the figure in step 3.

The resulting number is your BMI. Compare this BMI value with the weight status table below.

Example:

Enishaa weighs 150lbs and is 5 feet 4 inches tall. She wants to know if she is overweight.

Enishaa's height in inches is (5 * 12) + 4 = 66"

1. Using the first part of the formula we multiply her weight by 703. 150 * 703 = 105450

2. Using the second part of the formula we multiply Enishaa's height by itself. 66 x 66 = 4356

3. Finally we divide the first figure by the second.105450 / 4356 = 24.21

Enishaa's BMI is 24.21

We compare this value to the weight categories listed on the BMI table and find that she is of a normal weight.
