Grade Point Converter
Letters to grade points on an editable scale, percentages to letters using your own cutoffs — plus the quality points each course contributes.

How this calculator works
Grade points are the quiet currency of academic life: your letters are converted into them, multiplied by credit hours, and averaged into the GPA. The conversion itself is simple — but the exchange rate is set by your university, and no two handbooks are identical. This converter keeps the arithmetic neutral: you supply the scale and the cutoffs, it does the translation in both directions.
Two directions, one idea
Conversions
Letter → grade points: read from your scale
Percentage → letter: highest cutoff you meet wins
Quality points = credit hours × grade points
The percentage lookup works exactly like a grading table: cutoffs are minimum scores for each letter, and the letter you earned is the best one your percentage satisfies. The quality-points line connects this page to everything downstream — it is the same number that enters your semester GPA.
Worked example: what a letter is worth
Your handbook awards a B− 2.67 grade points. A 3-credit course with a B− therefore contributes 3 × 2.67 = 8.01 quality points. Push that course up to a B (3.00) and it contributes 9.00 — a gain of 0.99 quality points. In a 15-credit semester, 0.99 ÷ 15 adds about 0.07 to your SGPA. That is the entire mechanics of grade improvement: find the credit-heavy courses, move one letter, and the arithmetic does the rest.
Why the converter asks for your cutoffs
- Because they are not universal. A cutoff table from one institution is fiction at another — sometimes fiction by several percentage points, sometimes by an entire letter.
- Because courses override scales. Some courses curve or set their own boundaries; when that happens, use their table, not your faculty’s general one.
- Because accuracy compounds. The same letters feed every GPA calculation you make — a mis-mapped letter quietly distorts every average above it.
Where the points go next
Once letters map cleanly to points, the rest of the toolset snaps into place: the course total calculator determines the percentage, this page converts it into points, and the CGPA calculator carries the points into your cumulative record. One caveat throughout: these are your numbers and honest arithmetic — your university’s official scale and records are the final authority.
