A quick way to translate grades: enter a percentage and get the letter grade and GPA points it maps to on the standard US 4.0 scale — or enter a letter grade and see the percentage band it usually covers. Handy when you’re converting marks from one system to another.
Convert between a percentage, a letter grade, and GPA points on the standard US 4.0 scale. Type a percentage, or pick a letter grade, and read off the equivalent.
Band boundaries vary by school. This converter uses the common US 4.0 mapping — verify with your institution.
How the conversion works
On the standard US 4.0 scale, percentages sit in bands and each band gives a letter grade with fixed points. The common mapping the tool uses:
- A+ 97–100% → 4.0
- A 93–96% → 4.0
- A− 90–92% → 3.7
- B+ 87–89% → 3.3
- B 83–86% → 3.0
- B− 80–82% → 2.7
- C+ 77–79% → 2.3
- C 73–76% → 2.0
- C− 70–72% → 1.7
- D+ 67–69% → 1.3
- D 63–66% → 1.0
- D− 60–62% → 0.7
- F below 60% → 0.0
| Percentage | Letter | Points on the 4.0 scale |
|---|---|---|
| 97–100% | A+ | 4.0 |
| 93–96% | A | 4.0 |
| 90–92% | A− | 3.7 |
| 87–89% | B+ | 3.3 |
| 83–86% | B | 3.0 |
| 80–82% | B− | 2.7 |
| 77–79% | C+ | 2.3 |
| 73–76% | C | 2.0 |
| 70–72% | C− | 1.7 |
| 67–69% | D+ | 1.3 |
| 63–66% | D | 1.0 |
| 60–62% | D− | 0.7 |
| below 60% | F | 0.0 |
So an 88% drops into the B+ band and reads as 3.3 points. A 74% is a C at 2.0. Same percentage, different band boundaries at some schools — this is the common US convention, not a universal law.
One thing worth internalising before you use the number: this table is a lookup, not a curve. Your grade in a course is your percentage resolved into one of these bands, so a 3.3 is not “88% of 4.0”. 88% of 4.0 is 3.52, which sits above the top of the B+ band. Anywhere you see someone divide a percentage by 25 to get a GPA, that is the shortcut this tool exists to replace.
Use it as a rough tool, not a gospel
Every institution draws its own band cut-offs. One school’s A starts at 93, another’s at 90, a third’s at 85. The converter uses typical numbers so you get a sane estimate, but for anything official — an application, a scholarship, a transcript — use your school’s published rubric or just do the full conversion properly.
Also worth remembering: a single percentage converts to points, but your GPA is a credit-weighted average of many courses. This tool translates one number at a time; for a whole term use the GPA calculator. And if you’re working the other direction — a GPA back into a percentage — use the GPA to percentage converter.
Frequently asked questions
What GPA is 75 percent?
On this mapping, 75% sits in the C band — 2.0 points. Boundaries vary by school, so check your rubric before you rely on it.
What is a 4.0 GPA as a percentage?
Roughly 93–100%, since that band maps to an A/A+ and 4.0 points on this scale. Some schools make 4.0 start lower.
Does this converter work for other scales?
It uses the US 4.0 bands. The main calculator covers the weighted 5.0, Canada 4.3, India 10-point, Australia 7-point, and Nigeria 5-point scales if your grades are letters.
Is this converter accurate enough for applications?
For planning, fine. For anything official, no — use your institution’s published conversion and confirm with your registrar. Band cut-offs genuinely differ between schools.
