UK Degree Class to US GPA — First, 2:1, 2:2 Converted (2026)

Quick answer: A UK First-class Honours (1st) = US 4.0 GPA. Upper Second (2:1) = 3.7. Lower Second (2:2) = 3.0. Third (3rd) = 2.0. This is the WES (World Education Services) standard scale used by most US graduate-school admissions offices. The full conversion + the worked example for module marks is in our UK grade to GPA converter.

Of all the emails this site gets from international students, UK-degree questions are the most stressful — because UK universities do not issue GPAs at all. They issue degree classes, calculated from final-year module averages using boundaries each university sets for itself. Then a US grad-school application asks for a GPA on a 4.0 scale. The two systems do not speak the same language.

The good news: there is a standard, well-documented mapping that almost every US admissions office uses. WES publishes it, ECE publishes it, and most independent credential evaluators agree on the same numbers. This post walks through that scale, explains where it breaks down (looking at you, Oxford Mathematics), and tells you exactly what to put on a US application.

The conversion table

Here is the full UK degree class → US GPA mapping. It is identical to what the converter on this site uses and what WES sends in their official course-by-course report.

UK class	UK mark range	US letter	US 4.0 GPA
First-class Honours (1st)	70% and above	A	4.00
Upper Second-class (2:1)	60–69%	A−	3.70
Lower Second-class (2:2)	50–59%	B	3.00
Third-class (3rd)	40–49%	C	2.00
Ordinary / Pass degree	35–39%	D	1.00
Fail	below 35%	F	0.00

The big jump on this table is from 2:2 (3.0) to 2:1 (3.7) — 0.7 of a GPA point over a 10-percentage-point band. WES treats that gap as continuous in the official report, scaling marks inside the band linearly. So a UK 65% does not snap to 3.0 or 3.7 — it lands at roughly 3.35 in the official evaluation. The calculator on this site does the same thing.

Why the UK 70% threshold is so brutal

US students applying to UK universities for the first time often assume a 70% module mark is a "C" — because that is what 70% means in the US grading system. It is not. In the UK, 70% is the top mark. Less than 10% of students at most UK universities receive a First. A 50% UK mark is the threshold for the 2:2, which is a passing honours degree, not a failing grade.

This is because UK exam marks are scaled differently. UK examiners almost never give marks above 80 — and 90+ is essentially reserved for perfect answers in mathematical subjects. The distribution is compressed at the top. So a 70%+ mark is rare, even from top students.

The practical consequence: if you are converting individual module marks (not a degree class) to a US GPA, do not assume a UK 60% maps to a US 60%. It maps to a US A−. Use our converter in percentage mode to handle this correctly.

Edge cases the standard scale gets wrong

The WES scale is the right starting point. It is not the right ending point for every UK transcript. Here are the most common exceptions.

Oxbridge Mathematics and Engineering

Mathematics and some Engineering papers at Oxford and Cambridge are notorious for low average marks. In years where the average First-class mark is in the 65% range, the universities adjust the First boundary down to compensate. The official degree certificate still says "First-class Honours" — and US grad schools accept that, full stop.

If your transcript shows a class lower than the raw mark would suggest (e.g. you have a 68% average but a 2:1 because Oxford set the First boundary at 70% that year), report the class, not the mark. Admissions officers know about the boundary variation; the class is the official figure.

Scottish four-year degrees

Scottish honours degrees (MA Hons, BSc Hons over four years instead of three) use the same class system as English and Welsh universities. The conversion is identical. Scottish ordinary degrees (without honours) typically convert to the UK Pass class — a US 1.0 GPA equivalent. If your application asks for a GPA from a Scottish ordinary degree, mention this in your statement; admissions officers know the distinction.

Pre-1990s UK transcripts

Older UK university transcripts sometimes report raw percentage marks per module without an overall class — particularly from polytechnics, which were renamed universities in 1992. In that case use percentage mode in the converter and report the average across modules. If a 2026 admissions form insists on a class, "Upper Second" or "Lower Second" is the convention for the equivalent mark bands.

Distinction / Merit / Pass on Master's

Postgraduate UK degrees use a different scale: Distinction (70%+), Merit (60–69%), Pass (50–59%), Fail (<50%). These map to roughly the same GPA equivalents as their undergraduate counterparts:

• Distinction → 4.0 GPA equivalent
• Merit → 3.5 GPA equivalent
• Pass → 3.0 GPA equivalent

Note: Merit converts to 3.5, not 3.7. Postgraduate boundaries are more compressed than undergraduate.

What US grad schools actually want

The application form asks for a GPA. What the admissions office actually expects depends on the program.

Top-tier US PhD and Master's programs. They require an official WES or ECE course-by-course report. The report includes the GPA conversion plus a per-module breakdown. You cannot submit a self-converted GPA in place of the report; the application portal will reject it. WES costs about $200 and takes 1–3 weeks. Order it well before the deadline.

Mid-tier US Master's programs. Many accept either a WES report or a self-reported GPA on the application, then verify the transcript later. The GPA you self-report should match the WES standard — which is what this site's calculator outputs.

Direct-admission Master's at British-friendly schools. A handful of US schools (mostly in the Northeast, with strong UK exchange programs) accept the UK class directly and do not convert to GPA at all. They write "2:1 or equivalent" in their admissions criteria. If your school does this, do not over-convert — just report the class.

Business schools and law schools. They are the strictest. LSAC and the AACSB schools want WES reports without exception. Plan for the cost and the lead time.

Common mistakes UK students make

1. Self-reporting a 2:1 as 3.5. Some old conversion tables (pre-2010 versions of WES) used a flat 2:1 = 3.5 mapping. The modern WES scale uses 3.7. Use the current value.

2. Reporting the class but no GPA at all. US application forms have a GPA field that is required. Leaving it blank causes the application to be flagged as incomplete. Use the WES equivalent or the converter on this site, then explain the conversion in the additional information section.

3. Converting first-year and second-year marks too. UK degree class is calculated only from final-year and (sometimes) penultimate-year modules. First-year marks usually do not count. Convert the same way: use only the marks that contributed to the official class.

4. Forgetting the class boundary changes by university. Some London universities use 65% as the 2:1 boundary, not 60%. Check your transcript or call the registrar — and report what is on the transcript, not what you "earned" under a different scale.

5. Trying to map a Master's degree using undergraduate GPA equivalents. Distinction at MSc is not the same as First at BSc. Use the postgraduate scale (Distinction 4.0, Merit 3.5, Pass 3.0).

Frequently asked: what is a "good" UK degree for US grad school?

For most US Master's programs the minimum is 3.0 GPA, which equals a UK 2:2. That gets you past the cutoff, but it is below the median admit. The competitive median for top programs is a 2:1 (3.7) plus strong GRE/GMAT scores. A First (4.0) plus competitive test scores plus relevant research / work experience puts you in the strongest tier.

For US law school admissions (LSAC), the bar is higher: 3.5+ is competitive for the T14 schools, which means a strong 2:1 (mid-range mark) at minimum. Bottom-of-class 2:1s may need higher LSAT scores to compensate.
