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.

Things to know about the US school grading system

  • Since the grades are not given in percent, but in letters, each letter stands for a percentage range. However, the US school grading system does not have a uniform scale for this area. So it happens that 92% can be rated A in one country and B in another. However, the classification A (90-100%), B (89-80%), C (79-70%), D (69-60%) and F (60-0%) is relatively common.
  • If there is a year abroad in the USA, the previous grades have to be translated in some cases. German grades, for example, are often raised by one level due to their different values ​​and requirements. A 3 would then be a B, a 2 an A and a 1 an A +. At universities, however, performance is evaluated differently.
  • The percentile can also be used as a rating system for some tests. Grades are also given in percent, but the assessment is not based on the highest number of points that can be achieved, but on the highest number of points that was actually achieved. The highest number of points achieved is then considered the 100th percentile and the basis for all other evaluations. This creates greater competitive pressure. If a student reaches the 99th percentile, it means that only a better number of points was achieved. The 80th percentile got twenty better scores.

Due to the numerous differences between the various rating systems, it makes sense to obtain precise information from the respective educational institution before converting.
