Converting a GPA between the US 4.0 scale and the 10-point scale used in India and parts of Europe is a common need for study-abroad applications. The linear conversion is simple, but official evaluators do not always use it, so this guide gives both.
How it works
The linear formula is: 10-point score = GPA x 10 / 4, which is the same as GPA x 2.5. So 3.5 becomes 8.75 and 3.0 becomes 7.5. The reverse is GPA = 10-point score x 4 / 10. Official credential evaluators such as WES instead map letter grades and bands to US grades, which can give a different result from the linear formula, especially at the top of the scale. Always check what the receiving institution accepts.
Step by step
- Write down your GPA on the 4.0 scale.
- Multiply by 10 and divide by 4, or simply multiply by 2.5.
- Round to two decimal places for reporting.
- If the receiving institution uses band evaluation, look up its band table instead and report that figure.
- Label your conversion method whenever you submit it, so the reader knows which one you used.
- Never present a linear conversion as an official evaluation.
Worked example
GPA 3.7 x 2.5 = 9.25 on the 10-point scale. GPA 2.8 x 2.5 = 7.0. Reverse: a 10-point score of 8.2 converts to 8.2 x 0.4 = 3.28 on the 4.0 scale. Under a band-based evaluation, a 10-point score in the 9.0 to 9.49 band might map to about 3.90 on the 4.0 scale, while the linear formula gives 3.60 to 3.80, so the two methods can differ by a few tenths.
Common mistakes
- Multiplying by 10 but forgetting to divide by 4, which gives a score above 10.
- Mixing the two directions and converting 10-to-4 when you need 4-to-10.
- Presenting a linear result as an official WES-style evaluation.
- Rounding mid-calculation, which shifts the final figure.

Checklist before you finish
- Write down every input number first, with its unit, before you calculate anything.
- Work through the steps in order, and do not skip the unit conversions.
- Check the answer against the worked example above: is it the right size, and does the direction make sense?
- Round only at the end, and keep the unrounded figure for any follow-up calculation.
Practice with your own numbers
Pick three cases of your own and work each one by hand. First, try a simple round-number case you can check mentally. Second, try a realistic case with awkward numbers, the kind you will actually meet. Third, try an edge case, such as a very small or very large input, and confirm the answer still behaves sensibly. If any case gives a surprising result, re-check the units and the formula step by step before you trust it.
If your answer looks wrong
Most errors come from a small set of causes. Check that you used the same units throughout, that you divided where the formula divides and multiplied where it multiplies, and that you applied any percentage as a decimal. Check the order of operations: powers and brackets come before multiplication and division, which come before addition and subtraction. Finally, test the method on the worked example in this guide. If your method reproduces the example answer, the method is right and the inputs deserve a second look.
Quick tips
For applications, submit the official transcript and the conversion method together. If the institution has its own conversion table, use theirs, not the linear formula.
