UK to US / class to 4.0 scale
UK Degree Classification to US GPA
Updated 15 May 2026
UK degree classifications (First, 2:1, 2:2, Third) convert to US GPA differently across credential evaluation services. WES typically returns a 3.3-3.7 range for a 2:1; ECE typically returns approximately 3.5. The conversion that matters is the one your target US graduate programme uses. This page summarises the conversion methodologies and what US grad schools actually see when reviewing UK applications.
The UK classification system
UK undergraduate degrees are classified at completion into one of five bands based on the weighted average mark across the degree programme. The classifications are descriptive labels rather than direct numerical scores. The Quality Assurance Agency for Higher Education (QAA) publishes descriptors for each classification.
| Classification | Percentage threshold | WES US GPA |
|---|---|---|
| First-Class Honours (1st) | 70%+ | 4.0 |
| Upper Second-Class Honours (2:1 or II.i) | 60-69% | 3.3-3.7 |
| Lower Second-Class Honours (2:2 or II.ii) | 50-59% | 2.7-3.0 |
| Third-Class Honours (3rd) | 40-49% | 2.0-2.3 |
| Pass / Ordinary degree | Below 40% or non-honours pathway | Below 2.0 |
Conversion ranges from the published methodology of the WES iGPA Calculator and ECE. QAA descriptors via the QAA Frameworks for Higher Education Qualifications.
Why conversions differ
WES and ECE each apply their own methodology calibrated against different reference data. The fundamental challenge is that UK degree classifications are bands, not numerical scores. A 2:1 represents a range of underlying percentages (60-69%). The US 4.0 scale, by contrast, captures granularity at the half-point level (3.0, 3.3, 3.5, 3.7, 4.0). Translating from a band to a granular scale necessarily involves judgement about where within the band a typical UK degree sits.
WES's approach typically converts a 2:1 to a range of US GPAs depending on the percentage mark within the 60-69% band. A 2:1 at 68% might convert to 3.7; a 2:1 at 61% might convert to 3.3. The WES iGPA calculator can produce these granular conversions when given access to the underlying marks.
ECE's approach typically returns a single US GPA per UK classification, treating the classification as the operative signal rather than the underlying percentage. A 2:1 from ECE typically converts to approximately 3.5.
Both methodologies are reasonable. The conversion that matters for any specific application is the one the target US graduate programme uses. Some programmes require WES verification; others accept ECE; others apply their own internal conversion that may differ from both services.
What US grad schools actually do
US graduate-school admissions handling of UK degrees varies by programme. Common patterns:
Required credential evaluation: many US graduate programmes require WES or ECE verification of the UK degree. The credential evaluation service generates a verified report including the US GPA equivalent, which the admissions office uses directly.
Internal recalculation: some programmes apply their own internal conversion using either institution-specific guidance or general international-admissions handbooks. The internal conversion may differ from the WES or ECE figure by 0.1-0.3 grade points.
Direct evaluation: some programmes evaluate UK applicants based on the original UK transcript, classification, and institution, without converting to a US GPA. This is more common at programmes with substantial UK applicant volume and admissions readers familiar with the UK system.
Hybrid approach: many programmes use the credential evaluation as a starting point but apply institutional context (Russell Group vs non-Russell, well-known vs less-known UK university) to adjust the effective evaluation. Russell Group universities (Oxford, Cambridge, Imperial, UCL, LSE, etc.) typically receive more favourable institutional context.
Russell Group context
The Russell Group is a self-selected association of 24 leading research-intensive UK universities. Membership is a recognised indicator of institution-tier in US graduate-school admissions. A 2:1 from Oxford, Cambridge, Imperial, or UCL is typically read as more competitive than a 2:1 from a less-known UK institution.
The Russell Group effect is not formally captured in WES or ECE conversion methodologies, which apply the same band-to-GPA conversion regardless of institution. The effect operates at the admissions-reading level, where the institutional reputation contextualises the classification. A Russell Group 2:1 with strong supporting credentials (publications, research experience, well-known faculty letters) often outperforms a non-Russell Group First in US grad-school applications.
For US employers
US employer recognition of UK degree classifications is uneven. Multinational companies with UK operations typically understand the classification system; smaller US-only employers often do not. The practical advice for UK graduates applying to US jobs is to provide both the UK classification and the US GPA equivalent on the resume, often in parentheses: "BSc Economics, University of Manchester, 2:1 (US GPA equivalent: 3.5)". The dual format avoids the misreading that can happen when an unfamiliar credential is presented alone.
For US graduate-school applications, the WES or ECE conversion is typically the authoritative figure. The application should report the credential evaluation result rather than a self-converted estimate. The credential evaluation costs $200-$300 typically and is required for many programme applications anyway, so the cost is recoverable across multiple applications.
Educational reference. Not credential evaluation advice. Always use a credentialed service (WES, ECE, or equivalent) for the authoritative conversion required by US institutions.
