What it does
Type a CGPA out of 10, a percentage or a US GPA and see the same result on the other scales: percentage, CGPA, US 4.0, the Ontario (OMSAS-style) 4.0 table and the UK degree class. A second part works out a credit-weighted GPA from your courses and their grades.
Conversions between grading systems are never exact. Indian marks are usually lower than US marks for the same quality of work, so the page shows several US methods side by side instead of one “right” answer, and each university or evaluation service converts in its own way. Use this to get an idea, then follow the rule of the place you are applying to. When you are ready to apply, build your CV with the ATS resume builder and write the cover letter.
How to use it
- Pick what you have (CGPA, percentage or US GPA) and type the value.
- Read the results. For the topper method, add the highest CGPA in your batch.
- For a weighted GPA, add one row per course with its grade and credits.
What each setting does
- CGPA x 9.5: the CBSE rule for a percentage from a 10-point CGPA. Many universities have their own formula.
- Simple scale: CGPA divided by 10, times 4.
- Topper method: your CGPA divided by the best CGPA in the batch, times 4.
- Weighted GPA: each grade is turned into points, multiplied by the course credits, added up and divided by total credits.
Worked example
A CGPA of 8.4 is 8.4 x 9.5 = 79.8%. On the simple scale it is 3.36 out of 4.0. In the OMSAS-style table 79.8% is a B+ (3.3), and in the UK it is a First (70 and above). For the weighted GPA, A (4.0) with 4 credits, B+ (3.3) with 3 credits, A- (3.7) with 3 credits and B (3.0) with 1 credit gives (16 + 9.9 + 11.1 + 3) / 11 = 3.64.
FAQs
Which US method should I use? None of them is official. Evaluation services such as WES look at your transcript course by course. If an application asks for a GPA, give your own scale and the converted one, and say how you converted.
Is the UK class exact? The 70, 60, 50 and 40 boundaries are standard, but universities can round or weigh years differently.
Why can the OMSAS-style table differ for me? Each Ontario university has a scale of its own in the OMSAS table. This page uses the common percentage one.
Is my data kept? No. Everything stays in your browser and nothing is saved.
Where the numbers come from
- India: CBSE's indicative percentage is CGPA x 9.5 (CBSE announcement, reported by Deccan Herald; check cbse.gov.in). Universities use their own formulas (for example Mumbai University engineering, 7.25 x CGPA + 11), so use your university's rule if it has one.
- Canada: the OMSAS-style table (A+ 90 to 100 = 4.0, A 85 to 89 = 3.9, A- 80 to 84 = 3.7 and so on) is the Ontario medical school application scale as listed by OUAC (ouac.on.ca, OMSAS GPA pages) and by applicant guides; the exact table depends on your university's own scale. Checked 2026-11-10.
- US: the percentage to letter to points table is the common college scale (93 = A, 90 = A-, 87 = B+ ...). Schools differ.
- UK: the classes use the usual boundaries 70, 60, 50 and 40. The US equivalents are rough ranges quoted by many guides, not an official rule.
- Each university converts in its own way; check the official source of the place you apply to.
