Nigerian 5.0 CGPA Scale vs US 4.0 GPA Scale
Nigerian 5.0 CGPA Scale
Used across Nigerian federal universities under National Universities Commission (NUC) guidelines. The maximum achievable CGPA is 5.0. Degree classes: First Class ≥ 4.50, Second Class Upper 3.50–4.49, Second Class Lower 2.40–3.49, Third Class 1.50–2.39, Pass 1.00–1.49.
US 4.0 GPA Scale
The standard grading scale in the United States and many international institutions. Grades range from 0.0 (F) to 4.0 (A/A+). A cumulative GPA of 2.0 is typically required for academic good standing. Each letter grade maps to a fixed point: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.
Grade Comparison Table
| Performance Level | Nigerian 5.0 CGPA Scale | US 4.0 GPA Scale |

| First Class | 5.00 | 4.00 |
| 2nd Class Upper | 4.00 | 3.20 |
| 2nd Class Lower | 3.00 | 2.40 |
| Third Class | 2.00 | 1.60 |
| Pass | 1.00 | 0.80 |

GPA on a 5.0 scale to 4.0 GPA Formula
New GPA = (Original GPA ÷ 5) × 4
Both GPA scales are proportional — the formula rescales your GPA to the new maximum. A perfect score on one scale converts to a perfect score on the other; relative standing is fully preserved.
Example
4.38 on the 5 scale: (4.38 ÷ 5) × 4 = 3.50 on the 4 scale.
Conversion Examples
| GPA (5.0 Scale) | GPA (4.0 Scale) | Notes |
|---|---|---|
| 5.00 / 5.0 | 4.00 / 4.0 | First Class — maximum on both scales |
| 4.50 / 5.0 | 3.60 / 4.0 | Minimum First Class on Nigerian scale |
| 4.00 / 5.0 | 3.20 / 4.0 | Second Class Upper band |
| 3.50 / 5.0 | 2.80 / 4.0 | Minimum 2nd Class Upper |
| 2.40 / 5.0 | 1.92 / 4.0 | Minimum 2nd Class Lower |
Key Differences Between the Two Systems
Scale ceiling: The 5.0 maximum is 25% higher in absolute terms than the 4.0 maximum, but both represent the same level of academic excellence when considered proportionally.
Class label differences: Nigerian First Class (≥ 4.50/5.0) converts to approximately 3.60–4.0 on the US scale — squarely in Dean's List territory.
Graduate admissions guide: Many US programmes set a 3.0 GPA minimum; on the Nigerian 5.0 scale this corresponds to approximately 3.75 CGPA, within the Second Class Upper range.
NUC standardisation vs. institutional variation: Nigerian NUC mandates uniform cut-offs; in the US each institution sets its own Latin honours thresholds.
Tips for Accurate GPA Conversion
- 1
Always convert using the actual maximum from your transcript — if your institution uses a 4.3 or 4.5 scale, use the Custom GPA converter rather than the standard 4.0 converter.
- 2
Use proportional math when converting, not just raw label matching: a 3.5/4.0 is not the same academic performance as a 3.5/5.0.
- 3
For US graduate applications from Nigerian or other 5.0-scale institutions, always include the converted 4.0 GPA — many US admissions systems have no field for a 5.0-scale figure.
- 4
Always present your converted GPA alongside your original transcript — admissions officers are accustomed to seeing both, and it removes ambiguity.
- 5
For formal credential evaluations (WES, ECE, UK ENIC), the evaluating body will apply its own conversion method. Use this tool for self-reference, not as a substitute for official evaluation.
- 6
Use Batch mode to enter all your courses with credit hours and obtain a weighted average — more accurate than converting a single cumulative GPA.
