Nigerian CGPA to US 4.0 GPA Scale Converter
Applying to a scholarship or a school that asks for a "4.0 scale" GPA? Enter your CGPA exactly as it appears on your transcript and this tool converts it using the same proportional method credential evaluators like WES use — no guesswork, no under-selling a strong Nigerian result.

How this conversion works
Nigerian universities grade on a 5.0 or 7.0 scale, while US and many international scholarship portals expect a 4.0 scale. A direct percentage conversion (dividing by the scale and multiplying by 4) understates strong Nigerian results, because Nigerian and US grading distributions aren't shaped the same way.
Instead, this tool uses the proportional method common among credential evaluators:
US GPA = (Your CGPA ÷ Your Scale × 3) + 1
For example, a 4.20 out of 5.0 becomes: 4.20 ÷ 5.0 = 0.84 → 0.84 × 3 = 2.52 → 2.52 + 1 = 3.52 / 4.0.
| US GPA (4.0 scale) | Typical competitiveness |
|---|---|
| 3.7 – 4.0 | Exceptional — Ivy League and top global scholarships |
| 3.3 – 3.69 | Highly competitive — Commonwealth and many funded programs |
| 2.7 – 3.29 | Competitive — a solid match for many funded programs |
| 2.0 – 2.69 | Moderate — consider foundation/bridge routes or strengthening other parts of your application |
| Below 2.0 | Below most funding thresholds — a foundation year or additional coursework may help |
This is an estimate using a standard proportional method, not an official credential evaluation. Some scholarship portals and universities specify their own conversion table, and formal evaluators (WES, ECE, and others) may score your transcript slightly differently. Always follow the specific instructions on the application you're completing.
Where a 4.0 GPA scale actually matters
Almost every application that asks for "GPA on a 4.0 scale" falls into one of these groups:
| Category | Examples |
|---|---|
| US universities | Nearly all US undergraduate and graduate programs, from Ivy League schools (Harvard, Yale, Princeton, Columbia, Cornell, Brown, Dartmouth, Penn) to large public and private research universities (Stanford, MIT, Duke, Chicago, the UC system, and hundreds more) |
| Canadian universities | Most Canadian schools report on a 4.0 or 4.3 scale, including Toronto, UBC, and McGill |
| Major scholarship programs | Fulbright, Rhodes, Gates Cambridge, Schwarzman Scholars, Mastercard Foundation Scholars Program, Rotary Peace Fellowship, and many university-specific funding packages ask for a US-style GPA even when the applicant's home country grades differently |
| Programs that ask for a GPA equivalent | Chevening, DAAD, Commonwealth Scholarships, and Erasmus Mundus don't use a 4.0 scale themselves, but often ask applicants to state their GPA on one for comparison purposes |
This list is illustrative, not exhaustive — always check the specific university or scholarship's own application instructions for how they want your grade reported.
