Grade Conversion Chart — Letter, Percentage and GPA Point
Every letter grade this site tracks, read against five real scales at once: two US conventions plus what Columbia SPS, UBC and Maryland actually publish. A static reference table, no typing required.
Here is every letter grade this site tracks, already converted — five real scales, side by side, nothing to type in. Read down to your letter, then across to your scale. If your school isn't one of these five, it almost certainly isn't any of the others either — see “what this chart can't tell you” below.
Each row is where that letter starts. It runs up to, but doesn't reach, the percentage on the row above it — an 89 is still a B+ on the plus/minus convention even though 90 belongs to A−. A dash means the institution that publishes this scale doesn't publish that column at all, which is a real, common state, not a gap in this table.
The five scales
Plus/minus convention — A starts at 93
The scale most US syllabi land near, paired with the A+ = 4.0 point table. Widely used, published by nobody — which is why every cell below is editable.
| Letter | Starts at | Grade points |
|---|---|---|
| A+ | 97% | 4 |
| A | 93% | 4 |
| A- | 90% | 3.7 |
| B+ | 87% | 3.3 |
| B | 83% | 3 |
| B- | 80% | 2.7 |
| C+ | 77% | 2.3 |
| C | 73% | 2 |
| C- | 70% | 1.7 |
| D+ | 67% | 1.3 |
| D | 63% | 1 |
| D- | 60% | 0.7 |
| F | 0% | 0 |
Whole letters — A starts at 90
The other convention: no plus or minus grades, so each letter covers ten points and each is worth a whole number.
| Letter | Starts at | Grade points |
|---|---|---|
| A | 90% | 4 |
| B | 80% | 3 |
| C | 70% | 2 |
| D | 60% | 1 |
| F | 0% | 0 |
Columbia SPS — percentages and points together
The rare published scale carrying both columns at once. Note what it does at the edges: an A+ needs 98 and is worth 4.33, and a single D band covers a full ten points.
| Letter | Starts at | Grade points |
|---|---|---|
| A+ | 98% | 4.33 |
| A | 93% | 4 |
| A- | 90% | 3.67 |
| B+ | 87% | 3.33 |
| B | 83% | 3 |
| B- | 80% | 2.67 |
| C+ | 77% | 2.33 |
| C | 73% | 2 |
| C- | 70% | 1.67 |
| D | 60% | 1 |
| F | 0% | 0 |
UBC — percentages, no grade points
Cut-offs nothing like the US convention: an A starts at 85 and a 50 still passes. The calendar gives the percentage for each letter and no 4.0 equivalent beside it.
| Letter | Starts at | Grade points |
|---|---|---|
| A+ | 90% | — |
| A | 85% | — |
| A- | 80% | — |
| B+ | 76% | — |
| B | 72% | — |
| B- | 68% | — |
| C+ | 64% | — |
| C | 60% | — |
| C- | 55% | — |
| D | 50% | — |
| F | 0% | — |
Maryland — grade points, no percentages
The common US shape, and the reason this page exists: the registrar publishes what each letter is worth and never says what percentage earns it. That half is on your syllabus, written by your instructor.
| Letter | Starts at | Grade points |
|---|---|---|
| A+ | — | 4 |
| A | — | 4 |
| A- | — | 3.7 |
| B+ | — | 3.3 |
| B | — | 3 |
| B- | — | 2.7 |
| C+ | — | 2.3 |
| C | — | 2 |
| C- | — | 1.7 |
| D+ | — | 1.3 |
| D | — | 1 |
| D- | — | 0.7 |
| F | — | 0 |
Why there are five tables and not one
A single “grade conversion chart” would need there to be one conversion. There isn't — a percentage becomes a letter on your instructor's cut-off table, and a letter becomes a grade point on your registrar's point table, and the two are chosen independently. Columbia SPS is the rare institution that publishes both columns at once. UBC publishes the first column and not the second. Maryland publishes the second and not the first. The two conventions at the top aren't published by any institution — they're the shapes most US syllabi land near, which is exactly why they're the two most likely to be silently assumed by a page that shows only one table.
What this chart can't tell you
- Your school's own table, if it isn't one of these five. These are published, verifiable examples — not a standard, and not necessarily yours. Your syllabus has the percentage cut-offs; your registrar's grading page has the grade points.
- Where a receiving institution lands you. A transfer office, graduate admissions committee, or scholarship board applies its own scale to an incoming grade, and its answer is the only one that counts for that decision.
- Rounding. Whether 89.5 becomes 90 before it's compared to a cut-off is your instructor's call, usually unstated.
To convert one specific score — including entering it as a letter or a grade point instead of a percentage — use the Grade Scale Converter, which runs on this exact data and also shows the band a given score falls into. For the two-lookup structure behind all five tables above, this guide walks through it with a single worked example.

- UBC Vancouver Academic Calendar, Grading Practices — courses are normally graded A+ 90–100, A 85–89, A− 80–84, B+ 76–79, down to D 50–54 and F 0–49. Percentage cut-offs with no 4.0 column.
- University of Maryland, GPA Calculation — A+ and A both worth 4.0, A− 3.7, through to F 0.0, with no percentage equivalents published anywhere on the page.
Do it with your own numbers
Grade Scale Converter→Informational only — this is not your official grade. This page explains how the arithmetic works and cites the policies it refers to; it does not know your course. Your instructor records the real grade and your registrar keeps it, and where either disagrees with anything here, they are right.
