Converting grades between countries: CGPA, percentage, US GPA and UK class

Guide · Updated 2026-11-10

Why one grade can look very different on another country's scale, how each conversion method works, and how to work out a credit-weighted GPA from your courses.

A grade means something only inside the system that gave it. An 8 out of 10 in India, a 3.4 in the US and a 2:1 in the UK can describe similar work, yet the numbers look nothing alike. The GPA converter puts one result on several scales side by side, and it works out a credit-weighted average from your own course list. Once your grades are sorted, put them on your CV with the ATS resume builder and explain them in your cover letter. For marks inside a single course, such as tests worth different shares, the weighted grade is the better fit.

What it is

Every converter has to pick a bridge between scales. This one uses the percentage as the bridge.

• From an Indian CGPA (out of 10): percentage = CGPA × 9.5, the CBSE rule. Going back, CGPA = percentage ÷ 9.5.
• From a percentage: the percentage is used as it is.
• From a US GPA: the GPA is matched to the nearest letter on the US college scale, and the middle of that letter’s percentage band is used. A 3.4 is nearest to B+ (3.3), whose band runs from 87 to 89, so the bridge is 88%.

From the percentage, the tool reads off the US letter, the OMSAS-style letter used for Ontario medical school applications, and the UK degree class.

For a CGPA or percentage, it also gives two direct ways to reach a US 4.0 figure:

• Simple scale: CGPA ÷ 10 × 4.
• Topper method: CGPA ÷ (the best CGPA in your batch) × 4. It compares you with the top of your own class, which suits strict grading. It shows only when you type the batch’s best CGPA, and it never goes above 4.0.

Weighted GPA is a different job. A course with more credits counts for more:

GPA = (g₁ × c₁ + g₂ × c₂ + …) ÷ (c₁ + c₂ + …)

where each g is a course’s grade in points and each c is its credits.

How to use it

1. In Convert one result, choose what you have from I have a: a CGPA out of 10, a percentage or a GPA out of 4.0.
2. Type the Value. The results list fills in straight away.
3. For a CGPA or percentage, type the Highest CGPA in your batch if you know it, to see the topper method.
4. In Weighted GPA from your courses, pick how your grades are written: US letters or points up to 4.3, OMSAS-style letters, or points out of 10.
5. Fill one row per course with a grade and credits (the name is optional). Use Add a course for more rows, the x to remove one, Fill an example to see it work and Clear to start over.
6. Open The tables used to see every band behind the results.

A worked example

Meera has a CGPA of 7.6 out of 10, and the best CGPA in her batch was 9.1.

• Percentage: 7.6 × 9.5 = 72.2%
• Simple scale: 7.6 ÷ 10 × 4 = 3.04
• Topper method: 7.6 ÷ 9.1 × 4 = 3.34
• US college percentage scale: 72.2% is in the 70 to 72 band, C-, 1.7
• OMSAS-style table: 72.2% is in the 70 to 72 band, B-, 2.7
• UK: 72.2% is above 70, a First

The same record gives anything from 1.7 to 3.34 on a 4-point scale. That spread is the honest message: there is no single right answer, which is why you should follow the method the place you apply to asks for.

Now her last term, in points out of 10:

Weighted CGPA = (36 + 32 + 20 + 21) ÷ 13 = 109 ÷ 13 = 8.38 out of 10, and 8.3846 × 9.5 ≈ 79.7%. A plain average of the four grades would give 8.5, because it lets the 2-credit lab count as much as a 4-credit course.

Where it is used

• Applications abroad: a form asks for a GPA out of 4.0 and you studied on a 10-point scale. Give your own grade and the converted one, and say which method you used.
• Job forms: some employers ask for a minimum percentage or class. A rough figure helps you see whether you are near the line.
• Planning a term: add courses with the grades you expect and see what your weighted GPA would become.

Common mistakes

1. Using one method as if it were official. None of these is. Universities and evaluation services such as WES often study the transcript course by course.
2. Ignoring your university’s own formula. Many Indian universities publish their own rule instead of × 9.5. If yours has one, use it.
3. Mixing scales in the weighted part. Enter every grade in the scale you picked. A row the tool cannot read is skipped, and the result says how many were left out.
4. Reading a UK class as a GPA. The class is a band. The tool gives a rough US range for it, not a single figure.

Questions people ask

Why does a US GPA turn into a percentage in the middle of a band? A letter grade covers a range of marks, so the middle of that range is the fairest single guess.

Can I type A+ on the US scale? Yes. In the weighted part, A+ counts as 4.0, the same as A.

Why is my OMSAS-style letter higher than my US letter? The OMSAS-style table starts its bands lower (A+ from 90, B- from 70), so the same percentage lands on a better letter.
