What this calculator does
Schools in Pakistan, India and much of the world report marks as a percentage; universities in the United States and Canada, and many scholarship portals, ask for a GPA. This calculator bridges the two. It applies the exact inverse of the published GPA-to-percentage formula for the scale you pick, so a value converted here and then converted back on the GPA to Percentage calculator returns your original number.
Reverse formulas by scale
| Target scale | Formula | Example |
|---|---|---|
| 4.0 (US, HEC Pakistan) | (percentage ÷ 100) × 4 | 85% → 3.40 |
| 5.0 | (percentage ÷ 100) × 5 | 85% → 4.25 |
| 10-point (Indian universities) | (percentage ÷ 10) + 0.75 | 85% → 9.25 |
| 10-point (CBSE) | percentage ÷ 9.5 | 85% → 8.95 |
US letter-grade bands
US admissions offices rarely use the linear ratio. They map percentage ranges to letter grades and then to grade points. The most common table (used by many universities and by credential evaluators as a default) is below. Individual schools may shift a band by a point or two.
| Percentage | Letter | GPA |
|---|---|---|
| 93–100% | 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 |
Worked example: FSc marks to a 4.0 GPA
A student scored 934 out of 1100 in FSc, which is 84.9%. For a scholarship portal that wants a 4.0-scale GPA, the linear conversion is (84.9 ÷ 100) × 4 = 3.40. Under the band table the same 84.9% is a B (3.0). If the portal specifies “convert linearly” use 3.40; if it says “use your school’s letter scale” use the band. When unsure, report the percentage itself and let the office convert.
Worked example: percentage to a 10-point CGPA
An Indian student with 72% applying for a program that lists a “minimum 7.5 CGPA” needs the reverse of the general Indian formula: (72 ÷ 10) + 0.75 = 7.95, which clears the bar. Under CBSE the same 72% is 72 ÷ 9.5 = 7.58. Both clear 7.5, but the margin differs, so check which system the program means.
Common mistakes when converting percentage to GPA
- Using the band table for HEC transcripts. HEC Pakistan defines the linear ratio; a 3.4 CGPA is 85%, not a B.
- Forgetting the 0.75 offset. 80% is 8.75 under the general Indian formula, not 8.0.
- Mixing semester and cumulative figures. Convert the overall percentage if the form asks for CGPA, not one semester’s marks.
