If you are applying to the US from a UK degree, or to the UK from a US one, the first thing to accept is that there is no official conversion formula. A GPA and a UK classification are not the same kind of measurement wearing different clothes — they are built differently, and any table you find is an approximation, not a translation.
Why the systems do not map cleanly
A US GPA is a per-credit average on a 0–4.0 scale, usually calculated across every course you take, with each grade (A, B, C…) converted to a point value first. A UK classification is a percentage-based weighted average, calculated the way our weighted-average guide describes, then sorted into one of four bands (see our classification guide). The scales do not just use different numbers — grading severity, module structure and what counts toward the final result all differ by institution and country. Two students with “equivalent” ability can land on visibly different numbers simply because of how their system marks.
The rough table people actually use
Despite that, admissions offices, employers and students need some working approximation, and a rule-of-thumb table has become the de facto convention across UK and US higher-education advising:
- First-class honours ≈ 3.7–4.0 GPA
- Upper second (2:1) ≈ 3.3–3.6 GPA
- Lower second (2:2) ≈ 2.7–3.2 GPA
- Third-class honours ≈ 2.0–2.6 GPA
Treat these as a sanity check, not a certificate. They are useful for judging roughly where you stand on an application form; they are not what a university admissions system or an employer’s HR software will use to make a decision.
Where to get an official conversion
If a conversion needs to be official — for a visa, a professional licensing body, or an employer that requires formal proof — use a recognised credential evaluation service rather than a rule-of-thumb table:
- In the UK, Ecctis operates as the UK ENIC (the national agency for comparing international qualifications) and can produce a formal statement of comparability for a US degree.
- In the US, organisations such as World Education Services (WES) evaluate international credentials, including UK degrees, for US institutions, employers and immigration authorities.
Many universities also publish their own internal conversion tables for specific partner institutions — if you are applying via an exchange or dual-degree programme, check with your international office first, since they may already have an agreed mapping that overrides the general rule of thumb.
The practical takeaway
Know your real UK average before you worry about how it translates. UniGrade calculates your live weighted average and projected classification from your actual modules and marks, so you have an accurate number to convert from rather than a guess. Create a free account and see where you stand.
