Between the 5.0 and 10-point scales the maths is simple: double a 5.0 GPA to get the 10-point figure, or halve a 10-point GPA to get it on the 5.0 scale.
How to convert GPA between scales
To convert a GPA from one scale to another, divide it by the highest possible GPA on your current scale, then multiply by the highest GPA on the new scale:
Converted GPA = (Your GPA ÷ current scale maximum) × new scale maximum
Worked example: 4.0 to the 10-point scale
- Start with your GPA and its scale: 3.5 out of 4.0.
- Divide by the maximum: 3.5 ÷ 4 = 0.875. You have 87.5% of the highest possible grade points. This is not the same as a percentage mark.
- Multiply by the new maximum: 0.875 × 10 = 8.75 on the 10-point scale.
Going back works the same way: 8.75 ÷ 10 × 4 = 3.5. If you convert forward and back and land a hundredth or two away from where you started, that is rounding, not an error. A GPA rounded to two decimals on the 4.0 scale holds less detail than one on the 10-point scale.
Worked example: 5.0 to 4.0
A CGPA of 4.5 out of 5.0, common at Nigerian universities, gives 4.5 ÷ 5 = 0.9, and 0.9 × 4 = 3.6 on the 4.0 scale. As a quick check, the converted GPA should sit at the same point on the new scale as your original did on yours: 4.5 is 90% of the way to 5.0, and 3.6 is 90% of the way to 4.0.
Other scales
Scales such as 4.3, 7 or 20 points work the same way. Choose Custom scale and enter the highest GPA your university awards. For example, a 4.0 on a 4.3 scale converts to 3.72 on the 4.0 scale.
The converter needs a GPA to start from. If you don't have one yet, use the GPA calculator for a single semester or the CGPA calculator for your whole degree. If your transcript shows letters, convert your letter grades to GPA points first, and if a course isn't finished yet, work out your current course grade.
Who needs to convert their GPA
- International applicants. US and most Canadian universities ask for a GPA on a 4-point scale, so a 10-point or 5.0 GPA usually needs converting for application forms.
- Transfer students. If you move university or country partway through a degree, your new school may report grades on a different scale from your old transcript.
- Scholarship applicants. Many forms accept only one scale. A 7.8 out of 10, for example, is 3.12 on the 4.0 scale.
- Anyone facing a credential evaluation. Evaluators such as WES convert each course grade using their own country tables, so their GPA can differ from a proportional conversion. Use the converter as an estimate before the official report arrives.
Common mistakes when converting GPA
- Leaving out the scale. A 3.5 on a 4.0 scale and a 3.5 on a 5.0 scale are very different results. Always write the maximum next to your GPA, for example 3.5 / 4.0 or 7.0 / 10.
- Confusing GPA with a percentage. 3.5 out of 4.0 is 87.5% of the highest grade points, but that is not your percentage mark. Percentages need their own conversion (see below).
- Using a letter-grade table for a number. Looking up a band in a table (A = 4.0, B = 3.0) throws away where you sat inside the band. If you already have your GPA as a number, the proportional formula is more precise.
- Treating the result as official. A converted GPA is an estimate for planning and for forms that ask for one. Applications usually also need your original transcript, and some ask for an evaluation report.
- Picking the wrong target scale. US universities use 4.0, some Canadian universities use 4.3 or a 9-point scale, and UK universities generally use percentages and degree classes instead of a GPA. Check what the institution asks for before converting.
Converting other kinds of grades
This converter works with grade point scales only. Other grading systems need their own conversion:
- Percentage marks: turn a percentage into a GPA, or go the other way and convert a GPA to a percentage.
- IB Diploma scores: use the IB to percentage converter.
- UK A-levels: use the A-level to GPA converter.
FAQ
Is a 3.5 GPA on the 4.0 scale the same as 8.75 out of 10?
Mathematically, yes: both are 87.5% of the highest possible GPA. If the university you're applying to publishes its own conversion table, its figure may differ slightly, so use the table when there is one.
Why does my converted GPA look lower than expected?
A proportional conversion keeps your position on the scale, nothing more. If your university grades strictly, or a letter-grade table would round you up to the next band, the converted number can look lower than you expected. It still reflects where you actually sit on your own scale.
Do universities accept a converted GPA?
Many application forms ask you to convert your GPA yourself, and the proportional method is the usual way to do it. Always give your original GPA and scale as well, for example "8.2 / 10 (3.28 / 4.0)". Official evaluators such as WES work from your transcript with their own grade tables, so their figure can differ.
Should I convert each semester or just my final CGPA?
It makes no difference to the result. Proportional conversion is a straight multiplication, so converting your final CGPA gives the same answer as converting every semester and then averaging them. Converting once is simpler and avoids extra rounding.
How many decimal places should I give?
Two decimal places is the norm unless a form asks for something else. Use the decimal places setting in the converter to match what the application requires.
