UK Grades to US GPA Calculator
Enter your overall UK percentage to see the degree classification and its estimated US GPA equivalent, based on common evaluation bands.
Your UK result
Use your overall or final-year weighted percentage from the transcript.
Conversion bands used
| UK percentage | Classification | US letter | US GPA |
|---|---|---|---|
| 70–100% | First-Class Honours | A | 4.0 |
| 65–69.9% | Upper Second-Class Honours (2:1) | A- | 3.7 |
| 60–64.9% | Upper Second-Class Honours (2:1) | B+ | 3.3 |
| 50–59.9% | Lower Second-Class Honours (2:2) | B | 3.0 |
| 40–49.9% | Third-Class Honours | C | 2.0 |
| 0–39.9% | Fail | F | 0.0 |
Calculation Guide
How UK degree classifications map to US GPA
UK degrees are classified by overall percentage bands — First, Upper Second, Lower Second, Third — rather than a grade point average. US admissions offices typically map those bands to letter grades and a 4.0 GPA estimate.
This converter uses a common band mapping. Evaluation services and individual universities can assign different GPA values to the same UK result, so treat the output as an estimate.
How to use the calculator
- 1
Find your overall percentage
Use the weighted final percentage from your transcript, not a single module mark.
- 2
Enter the percentage
The converter returns the degree classification, the US letter equivalent, and the estimated GPA.
- 3
Compare the band table
Check where your percentage sits within the band — a 69.9 and a 70.0 convert differently.
GPA formula
US GPA = band value for the degree classification containing your percentage
Band mapping: First (70+) = 4.0, high 2:1 (65-69) = 3.7, 2:1 (60-64) = 3.3, 2:2 (50-59) = 3.0, Third (40-49) = 2.0, below 40 = 0.0.
UK conversion example
A student graduates with 67% overall:
| UK percentage | Classification | US letter | US GPA |
|---|---|---|---|
| 67 | Upper Second-Class (2:1) | A- | 3.7 |
A 67% overall maps to an estimated 3.7 US GPA.
Conversion caveats
- Scottish, integrated masters, and pass/fail degrees may classify differently — check the award regulations.
- US graduate programs frequently require a course-by-course evaluation rather than a self-conversion.
- Two students in the same band receive the same estimate even at opposite edges of the band.
Frequently asked questions
Is a UK First really a 4.0?
Most conversion tables treat a First-Class Honours (70%+) as equivalent to an A or 4.0, but the rarity of high UK marks means evaluators often view a First as stronger than a proportional conversion suggests.
What if my university does not award percentages?
Use your degree classification with the band table on this page, or ask the target institution which evidence it prefers.
Do US colleges accept my own conversion?
Many ask for the original classification plus an official evaluation. Self-converted numbers are for planning, not for official submission.
Where does the 3.7 for a high 2:1 come from?
Common evaluation practice splits the 2:1 band: marks nearer a First convert to an A- (3.7) and marks nearer 60 convert to a B+ (3.3).
