# How do I convert SGPA to percent

## Convert grades to percent - this is how you calculate like in the US school grading system

If you would like to specify grades in percent or to calculate as in the US school grading system, for example for a year abroad, you will find instructions with calculation examples here.

The US school grading system is not uniform across the country and can vary from school to school. The grading does not take place with the numbers 1 to 6, but is indicated with the letters A to D for passed and an F (failed) for failed. The letters stand for the percentages achieved or, more precisely, for a percentage range. However, these percentage ranges also differ.

### Calculate grades as a percentage

1. Since the grades each represent a percentage range, you cannot convert them retrospectively into exact percentages. You need the highest possible number of points and the points actually achieved in order to calculate the percentages.
2. Divide the points achieved by the total number of points. For a test in which 45 points, out of 60 possible points, were achieved, the first calculation looks like this: 45/60 = 0.75.
3. Now multiply by the factor 100 to get the percent: 0.75 * 100 = 75%.
4. On most American grading scales, 75% corresponds to the grade C. If you had achieved 59 out of 60 points, you would have received 98.33% as a result and thus would have an A +.
5. If you want to convert several grades into percentages, i.e. not just for one test, but for the entire performance in a semester or half-year, you should write down the individual grades in percent. Then add up the results and divide the result by the number of grades. For example, if you received five ratings corresponding to 75%, 80%, 83%, 93% and 95%, the invoices would be: 75 + 80 + 83 + 93 + 95 = 426; 426/5 = 85.2%. In the US school grading system, this corresponds to a B.

### Calculate the GPA

Another US grading system that determines access to courses and secondary schools as a general average is the GPA. The Grade Point Average is a grade point average, in which the grades are not given in percent, but in points. An A receives the point value 4, a B = 3 points, a C = 2 points and a D = 1 point. The respective point values ​​are multiplied by the credits, i.e. the weekly hours, and then divided by the number of subjects. That sounds complicated, but you can easily calculate it. Here's an example:

1. If you have completed 5 credits each and the subjects Mathematics with A, Biology with B and English with C, multiply the point values ​​by the 5 credits. 5 * 4 = 20; 5 * 3 = 15; 5 * 2 = 10.
2. Then add the results: 20 + 15 + 10 = 45.
3. You have three subjects with 5 credits each, for a total of 15 credits. Now divide the result by this total number of credits. 45/15 = 3.0.
4. You will get a GPA of 3.0.

The GPA is also not uniform. However, the variant presented here is the most widespread.
