A percentage is your raw score out of 100. A GPA is a grade-point average usually built from letter grades. The two measure related things, but there is no single universal formula between them — conversions depend on your country and school.
The difference explained
Percentage: exact marks, e.g. 87%. Easy to compare within one course where all tests are marked the same way.
GPA: the average of grade points (A = 4.0, B = 3.0, etc.) weighted by credits. It flattens precise marks into broad bands so coursework of different types can be averaged fairly.
Typical US-style mapping
As a rough guide on the 4.0 scale:
- A: 90–100 → 4.0
- B: 80–89 → 3.0
- C: 70–79 → 2.0
- D: 60–69 → 1.0
- F: below 60 → 0.0
But institutions draw the cut lines at different percentages, and other countries use entirely different systems (India’s 10-point, Australia’s 7-point, Nigeria’s 5-point). A 75% that is an A+ in one system can be a C in another.
Why GPA is used instead
GPA survives comparison across courses and schools better than a raw percentage, because it averages within each school’s own grading bands. That’s why transcripts, scholarships, and admissions usually ask for GPA — and why it’s risky to convert your percentage with a random online formula.
Convert responsibly
If you need a conversion (for example, for an international application), use an official scale or a recognised service rather than guessing. To average grades that are already in GPA form, the GPA calculator and cumulative GPA calculator will do the weighted math for you.
