Irish degree results come in classifications, not GPAs. Your transcript says First Class Honours or Second Class Honours Grade 1, and the American form you are filling in wants a number out of 4.0 with no box for “this is a word, not a number”.
This converter bridges that gap. Pick your classification, press Convert Classification, and it hands back the US 4.0 figure plus a sentence you can drop into an application field without rewriting it. Five classifications are covered, from First Class down to Pass, which is the range Irish institutions actually award.
It is a mapping, not an evaluation. Useful for working out where you sit before you start applying, and worth knowing is approximate before you send anything anywhere official.
Convert your Irish degree classification to a US 4.0 GPA equivalent.
How it works
Choose the classification that matches your transcript and press Convert Classification. A 2:1 comes back as “US GPA: 3.3 / 4.0” with a summary line underneath reading “Second Class Honours Grade 1 (2:1) converts to a US GPA of 3.3 on the 4.0 scale.” Press Reset and both the selection and the result clear, which is handy when you are checking a friend’s result as well as your own.
| Irish classification | US GPA |
|---|---|
| First Class Honours | 4.0 |
| Second Class Honours Grade 1 (2:1) | 3.3 |
| Second Class Honours Grade 2 (2:2) | 2.7 |
| Third Class Honours | 2.0 |
| Pass | 1.0 |
The gaps are not even, and that is deliberate rather than an error. The distance from First to 2:1 is 0.7, from 2:1 to 2:2 is 0.6, then 0.7 and 1.0 down to Pass. A classification scale is a set of labels, and squeezing labels into a continuous scale always produces a few lumpy steps.
A worked example
Two students finish side by side, one on 68% and one on 61%. Both land in Second Class Honours Grade 1, so both come out at 3.3, and the converter cannot see the seven percentage points sitting between them. That is the honest limit of this kind of tool: it is accurate about the label and blind to everything inside it.
Now a third student finishes on 70%, crosses into First Class, and comes out at 4.0. Half a percent of marks moved and the reported GPA jumped 0.7. If a US program wants a 3.5, neither of the two 2:1 students reaches it through this number no matter which end of the band they finished at, so a personal statement, a portfolio, or a strong reference has to do the work that the number cannot.
Common mistakes and honest caveats
The percentage bands behind these labels differ by institution. The commonly cited split is 70% and above for First, 60 to 69% for a 2:1, 50 to 59% for a 2:2, and below that for Third and Pass, but your own university’s regulations are the ones that apply, and some use different cut-offs or add honours variants on top. Check the handbook before you assume a band.
Second: US admissions teams usually want the conversion done their way. Many ask for a credential evaluation from a service such as WES, and the evaluator’s figure is the one that counts on your file. Treat this number as a way to know where you stand while you plan, not as the final word on your transcript.
Third, a classification is one line covering an entire degree. A transcript full of mid-50s and a transcript full of high-60s can both read 2:2, and any committee reading your modules will notice what this converter cannot show. Put the classification in the field it belongs in and let the rest of the application carry the detail.
One more thing worth knowing: an Irish honours degree and an ordinary degree are different awards at different levels. Do not convert an ordinary degree as though it were an honours classification, and if a form asks about degree level, answer that question separately from the GPA one.
Other tools
Grading works differently everywhere, and the differences are the interesting part. The Kenya KCSE points calculator adds up a 12-point scale across seven subjects, the Malaysia CGPA converter handles the 4.0 scale used there, and the major GPA calculator pulls a GPA out of just the courses in your subject.
Frequently asked questions
What counts as a good classification in Ireland?
First Class is the top award. A 2:1 is the grade most graduate programmes and schemes that specify a result ask for, and a 2:2 is a solid, normal result that plenty of people build careers from.
What is the difference between a 2:1 and a 2:2?
Here it is 0.6 of a GPA point. On paper the usual gap is roughly ten percentage points of average, though the exact bands come from your institution rather than from any national rule.
Is this an official credential evaluation?
No. It is a straight mapping from a classification to a number, with nothing checked against your transcript and no document issued. An evaluation service gives you a report, this gives you a figure.
Will a US university accept this number as it is?
Some will, many will not, and the programme’s own instructions decide it. Use this to know where you stand, then follow whatever conversion method the application asks for.
My transcript shows a percentage, not a classification. What now?
Work out your classification from your university’s published bands first, then put that classification into this converter. The percentage on its own does not map to a GPA here.
