Percentage to GPA: International Conversion Guide

By Taylor Annanders, M.Ed.

Quick answer. There is no universal percentage-to-GPA formula because grading conventions vary by country. A 75% in the UK is a strong First-class honour (≈ 4.0). A 75% in China is a B (≈ 3.0). A 75% in India is a strong distinction (≈ 3.5). Always convert using your country's local convention, not a global rule.

Why a single formula doesn't work

The naive conversion — GPA = (percentage / 100) × 4 — gives wrong answers everywhere.

A 60% under that formula maps to 2.4 GPA. In the UK, 60% is a Second-class Upper honour, roughly a 3.3 GPA. In Germany, 60% on a 100-scale converts to a 2.7 on the inverted German scale, which is around a 2.7 US GPA. In China, 60% is a passing grade — closer to 2.0 US GPA.

Same input, three correct answers in three countries. The local grading convention is the missing variable.

The two valid approaches

When US universities and employers need to convert international transcripts to a 4.0 GPA, they use one of two approaches:

1. Credential evaluation service (WES, ECE, IEE)

Third-party evaluators apply country-specific tables built from years of analyzing transcripts. The most common services:

You submit your transcript; they return a "US equivalent" GPA on the 4.0 scale. The result is what selective US grad programs and many employers actually trust.

2. Institution-specific table

Many US universities publish their own conversion tables — they don't trust WES or ECE for every country. Always check the receiving institution's website before converting on your own.

A self-converted GPA without WES/ECE backing is fine for casual contexts (LinkedIn, informal applications) but rarely accepted for selective programs.

Country-specific conversion tables

The following tables show common approximations. They are not official. For applications, get a WES or ECE evaluation.

India (percentage from CGPA × 10 or raw university %)

| Indian % | US GPA approx | |---|---| | 85-100% | 4.0 (A) | | 75-84% | 3.7 (A-) | | 70-74% | 3.5 (B+) | | 65-69% | 3.3 (B+) | | 60-64% | 3.0 (B) | | 55-59% | 2.7 (B-) | | 50-54% | 2.3 (C+) | | 40-49% | 2.0 (C) | | Below 40% | Fail |

Note: Indian top-tier universities (IITs, IIMs) grade harder than this table suggests. A 75% at an IIT is roughly equivalent to an A at most US universities. See our CGPA to GPA guide for the CGPA conversion.

China (raw university %)

| Chinese % | US GPA approx | |---|---| | 90-100% | 4.0 (A) | | 85-89% | 3.7 (A-) | | 82-84% | 3.5 (B+) | | 78-81% | 3.3 (B+) | | 75-77% | 3.0 (B) | | 72-74% | 2.7 (B-) | | 68-71% | 2.3 (C+) | | 64-67% | 2.0 (C) | | 60-63% | 1.0 (D) | | Below 60% | Fail |

WES uses a similar table for Chinese transcripts. Note: Chinese universities grade conservatively — a 90% is rare and prestigious.

UK (degree classification)

| UK % | Classification | US GPA approx | |---|---|---| | 70%+ | First-class honours | 4.0 | | 60-69% | Upper second (2:1) | 3.7 | | 50-59% | Lower second (2:2) | 3.0 | | 40-49% | Third class | 2.7 | | Below 40% | Fail | — |

UK percentages are scaled differently — a 75% is exceptional, not just "above average." Don't apply US-style mappings.

Germany (inverted 1.0-4.0 scale, where 1.0 is best)

German grades use a 1.0-4.0 scale where lower is better. Convert with the modified Bavarian formula or institution-specific tables.

| German grade | Description | US GPA approx | |---|---|---| | 1.0-1.3 | Sehr gut (very good) | 4.0 | | 1.4-1.7 | Gut (good) | 3.7 | | 1.8-2.3 | Befriedigend (satisfactory) | 3.3 | | 2.4-3.0 | Ausreichend (sufficient) | 2.7 | | 3.1-4.0 | Mangelhaft (poor) | 2.0 | | Above 4.0 | Fail | — |

France (out of 20)

| French grade | US GPA approx | |---|---| | 18-20 | 4.0 (exceptional) | | 16-17 | 3.7 (very good) | | 14-15 | 3.3 (good) | | 12-13 | 3.0 (satisfactory) | | 10-11 | 2.0 (pass) | | Below 10 | Fail |

French universities almost never give grades above 17/20. A 14/20 is a strong B+ to A-.

Brazil (out of 10)

| Brazilian grade | US GPA approx | |---|---| | 9.0-10.0 | 4.0 | | 8.0-8.9 | 3.7 | | 7.0-7.9 | 3.0 | | 6.0-6.9 | 2.3 | | 5.0-5.9 | 2.0 | | Below 5.0 | Fail |

Other percentage countries (general approximation)

For countries with standard 0-100% grading and a 60% pass threshold (Saudi Arabia, Egypt, Mexico, much of Latin America), the simple proportion is close enough for informal use:

GPA ≈ (percentage − 50) / 12.5

So 90% → 3.2, 80% → 2.4. Always verify with the institution or with WES.

The WES iGPA method (how the pros do it)

WES converts in three steps:

  1. Course-by-course mapping. Each course on your transcript is mapped to a US letter grade using a country-specific table.
  2. Credit weighting. WES assigns US credit-hour equivalents to each course based on contact hours and academic intensity.
  3. Standard GPA formula. WES applies the standard formula: ∑(grade points × credits) / ∑ credits.

The result is the "WES iGPA" reported on the credential evaluation. Most US selective programs accept this number at face value.

You can preview your WES iGPA for free on the WES iGPA Calculator before paying for a full evaluation.

Common questions

Can I use a single formula for my country's percentage to US GPA?

For informal use, yes — use the country's table above. For a formal application, get a WES or ECE evaluation. Self-converted GPAs are rarely accepted by selective programs.

Why does my country's "good" grade convert to a lower GPA than I expected?

US grading inflation. Over the past 30 years, US universities have raised their average GPAs significantly — the "good" tier in the US is now 3.5+ where it used to be 3.0. Many other countries haven't followed. A grade that's "very good" in your country may correspond to "good" by US 4.0 standards.

Should I report my native percentage or the converted GPA?

Most US applications ask for both: your raw grades in your native scale and a converted GPA. Submit your native transcript, get a WES/ECE evaluation, and report both the native percentage and the WES iGPA.

What if my country uses a 10-point scale?

If it's Indian CGPA, use our CGPA to GPA guide. If it's another 10-point scale (Brazil, Spain), use the country-specific table above or contact WES.

Why don't WES and ECE give the same number?

They use slightly different conversion tables and credit-weighting rules. The difference is usually less than 0.1 GPA. Pick whichever your target institution accepts — most accept both.

Do US universities have their own conversion tables?

Yes, many top universities (Stanford, MIT, Berkeley, etc.) publish institution-specific conversion tables that supersede WES. Always check the receiving school's website before relying on a generic conversion.
