How to Calculate BMI

BMI, which stands for Body Mass Index, is a measurement tool that allows you to have an idea on whether your weight is appropriate for your height. It will indicate whether you are overweight, underweight, or at a healthy weight. The steps listed below will teach you how to calculate BMI manually.

Step One: Get your weight.

For this step, you will need a bathroom weighing scale to get your weight in pounds. Take note of your exact weight.

Step Two: Measure your height.

To do this, you have to stand straight against a wall and put a pencil mark that is at the same level as the top of your head. Starting from the floor to the pencil mark, use a tape measure and take note of the measurement in inches.

Step Three: Get the square of your height.

To get the square, you have to take your height and multiply the number by itself. For example, your height is 66 inches, when you multiply 66 by 66 the product will be 4356. I need you to take note of that number.

Step Four: Divide your weight by the square of your height and round off to two significant figures.

For this step, you will need to divide your weight in pounds by the square of your height that we have calculated in the previous step. So for example, you have a weight of 130 pounds and we divided that by 4356, the answer would be 0.030.

Step Five: Multiply the answer by 703.

You will get your body mass index by multiplying the answer you got on the previous step by 703. So 0.030 multiplied by 703 is 21.09.

How to Interpret the Result

  1. If your BMI is less than 18.5, you are considered to be underweight for your height.
  2. If your BMI is within the range of 18.5 – 24.99, you are at a healthy weight.
  3. If your BMI is greater than or equal to 25, you are overweight.
  4. If your BMI is equal to or greater than 30, it indicates obesity.

Tips:

  1. In measuring your height, don’t forget to take off your footwear and hat.
  2. Make sure that when you use the tape measure, it should be flat against the wall.
  3. If you got a BMI of 30 or greater, consider consulting with your physician.

Grade point average or GPA indicates how well a student is doing at a certain educational institution. Just as the educational system varies across the globe, the method on how to calculate grade point average varies from country to country, school to school. Luckily, the basic underlying premises are the same so the steps are somehow similar.

How to calculate GPA - By average:

1. Identify the grading scale.

The most commonly used is a four pointer scale such as A=4, B=3, C=2, D=1 and F=0.

In cases of the + and – symbols, this means that the precise points from the grade book has been factored in.

2. Collect the letter grades from different subject areas.

3. On a sheet of paper jot down the correct letter grade and point value for each using the four-point scale.

Approximately use add a 0.33 for a grade that has + and subtract it from a grade that has -. For instance, an A+ would be 4.33 while an A- would be 3.67.

4. Add up the values.

5. Take the sum and divide it by the number of classes.

6. The quotient is the GPA.

How to calculate GPA - By credits:

In some cases, some subjects get more credit than others.

1. Identify the grading scale.

The most commonly used is a four pointer scale such as A=4, B=3, C=2, D=1 and F=0.

In cases of the + and – symbols, this means that the precise points from the grade book has been factored in.

2. Collect the letter grades from different subject areas as well as the credit hours.

3. Assign the correct scale value for every letter grade like in step 3 above and write them down.

4. Multiply the credits with the corresponding scale value.

5. Add the number of credits.

6. Add the number of grade values.

7. Divide the grade values by the credits and the quotient is the GPA.

It is important to ask the school administration for the correct grading system and number of decimal places they use before going ahead and computing. Also consider that some institutions make use of sessional GPA and others make use of cumulative GPA.
