The result is a standard letter-grade-to-Nigerian-class estimate you can use as a quick reference before any official credential evaluation.
How to Use the Letter Grade to Nigerian Class

2Click Convert
Press the "Convert" button to calculate the result. The converter instantly returns your Nigerian degree class (e.g., if you enter B+ you should see approximately Second Class Upper (2:1)).
3Read Your Result
Your Nigerian degree class appears in the result panel on the right sidebar with a performance badge (Excellent, Good, etc.). You can use this value on applications, CVs, or academic forms that require Nigerian degree class format.
4Batch Mode — Convert Multiple Grades

US Letter Grade vs Nigerian degree class
US Letter Grade
A letter (with optional +/−) representing academic performance. A+ and A represent excellent work (4.0 GPA equivalent), B+ through B− represent above-average work, C represents average performance, D is below average but passing, and F is failing. Used by most US colleges and K–12 schools.
Nigerian degree class
Nigerian degree class is the target grading scale returned by this converter.
Grade Comparison Table
| Performance Level | US Letter Grade | Nigerian degree class |
|---|---|---|
| Excellent | A / A+ | 4.0 |
| Very Good | A− | 3.7 |
| Good | B+ | 3.3 |
| Above Average | B | 3.0 |
| Average | C | 2.0 |
When You Need GPA Conversion
- 1You need to express a US letter grade as a numeric GPA on an application form.
- 2Translating a GPA into letter grades for institutions that only accept letter format.
- 3Understanding how a letter grade maps to international grading equivalents.
- 4Comparing your academic record to honour roll or scholarship GPA thresholds.
- 5Applying to graduate programmes that list admission requirements in letter-grade terms.
Letter Grade to GPA Conversion Scale
A/A+ = 4.0 · A− = 3.7 · B+ = 3.3 · B = 3.0 · B− = 2.7 · C+ = 2.3 · C = 2.0 · D = 1.0 · F = 0
There is no single arithmetic formula — letter-to-GPA conversion uses a fixed lookup table. These values are the US standard used by most colleges. Note: some schools do not award A+ separately and cap the scale at 4.0.
Example
A student earning B+, A−, C, B receives 3.3 + 3.7 + 2.0 + 3.0 = 12.0 total grade points. Divided by 4 courses = 3.0 GPA.
Conversion Examples
| US Letter Grade | Nigerian Degree Class | Notes |
|---|---|---|
| A / A+ | 4.0 | Excellent — highest possible |
| A− | 3.7 | Very Good |
| B+ | 3.3 | Good — above average |
| B | 3.0 | Above average |
| C | 2.0 | Average — minimum good standing at many schools |
Key Differences Between the Two Systems
Granularity: Letter grades with +/− modifiers split a GPA range into thirds (e.g. A−, A, A+ all map to 3.7–4.0), giving more descriptive meaning than a bare GPA number.
A+ treatment varies: Some US schools do not distinguish A+ from A (both = 4.0); others award A+ a 4.3 (Canadian style). This tool uses the common US standard where A+ = 4.0.
International readability: Letter grades are well understood in North America but can confuse international employers unfamiliar with the +/− modifier system.
Cumulative vs. per-course: A GPA summarises many courses weighted by credits, while a letter grade represents one course's performance.
Tips for Accurate GPA Conversion
- 1
Check whether your school awards A+ as a separate grade worth 4.3 (Canadian style) or caps it at 4.0 (US standard). This tool uses the common US standard where A+ = 4.0.
- 2
When converting GPA to a letter grade, remember that a letter grade is a range — a 3.1 GPA and a 3.29 GPA are both a B, despite feeling numerically different.
- 3
For graduate school applications, include your exact GPA number alongside the letter grade equivalent — it provides more information to the admissions committee.
- 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.
