Why GPA conversion matters
When UK students apply for postgraduate programmes or jobs in the United States, they’re often asked to provide their **GPA** instead of a degree classification. However, the UK and US systems use different scales — UK degrees rely on percentages and classifications, while the US uses a 4.0-point GPA scale.
This article helps you accurately convert your results using common equivalence tables used by universities and credential evaluators like **WES (World Education Services)** and **ECE (Educational Credential Evaluators)**.
Standard UK degree classifications
- First Class Honours — typically 70% or above
- Upper Second Class (2:1) — 60% to 69%
- Lower Second Class (2:2) — 50% to 59%
- Third Class — 40% to 49%
- Fail — below 40%
If you’re unsure of your percentage, you can use our degree calculation guide to find it before converting to GPA.
UK to US GPA conversion table
This table shows the approximate equivalences most accepted by international admissions offices (source: WES, verified 1 Oct 2025):
| UK Classification | UK Percentage | Approx. US GPA Equivalent | US Letter Grade |
|---|---|---|---|
| First Class | 70–100% | 3.7–4.0 | A / A+ |
| Upper Second (2:1) | 60–69% | 3.3–3.6 | B+ |
| Lower Second (2:2) | 50–59% | 2.7–3.2 | B / B– |
| Third Class | 40–49% | 2.0–2.6 | C |
| Fail | Below 40% | 0.0–1.9 | F |
Different US universities may interpret these slightly differently, but these are widely recognised conversions.
Example: converting a UK percentage to GPA
Let’s say your final weighted average is 67.5% — a strong 2:1 classification.
67.5% → falls in the 60–69% band = Upper Second (2:1) Equivalent GPA ≈ 3.5 on a 4.0 scale
In a postgraduate admissions form, you would enter:
- Degree classification: Upper Second Class (2:1)
- Equivalent GPA: 3.5 / 4.0
If your score is just below a classification boundary, check percentage to classification to understand borderline conversions.
How US universities view UK grades
Most US institutions know that UK grading is tougher and more compressed. For example, a UK student with 68% is often seen as equivalent to an American student with a 3.6 GPA, even though 68% may look modest by US standards.
Admissions offices consider:
- Relative difficulty of UK marking
- University ranking (e.g., Russell Group weighting)
- Final-year performance and dissertation scores
Many universities also use external verification services like WES.org or ECE.org to officially assess UK transcripts for GPA equivalence.
Weighted vs unweighted GPA conversions
Just like in the UK, GPA can be calculated as either weighted (based on credit hours) or unweighted (equal weight). If your modules had different credit values, the mixed credit weighting guide explains how to apply this principle before converting to GPA.
Checklist — converting your marks correctly
- ✔️ Calculate your final weighted percentage using the Grade Calculator.
- ✔️ Match your percentage to the GPA table above.
- ✔️ Include your UK classification (e.g., 2:1) in any application forms.
- ✔️ Verify conversions with your university’s transcript office or WES.
- ✔️ Keep both UK and GPA formats on your CV for clarity.
FAQ
Q: Is there an official UK-to-US GPA conversion formula?
A: No single formula exists, but evaluators like WES use standard percentage ranges to estimate GPA equivalents. The table above follows their most recent model (Oct 2025).
Q: What GPA is a 2:1 in the UK?
A: Typically between 3.3 and 3.6, depending on your exact percentage and institution.
Q: Can I use UniGradeCalculator for GPA conversion?
A: Yes — calculate your final weighted percentage, then match it to the US GPA scale shown here.
Q: Are UK grades harder than US grades?
A: Generally, yes. UK marking is stricter, with fewer students achieving above 70%. A UK 2:1 is roughly equal to a US B+/A– range.
