The "standard" scale (93/90/87/83...) with plus/minus grading is widely used — Fairfax County Public Schools, for example, uses 93–100 for an A — though at colleges each instructor or department usually sets the cutoffs in the syllabus. The "alternate" scale (90/80/70/60, whole letters only) is common at schools that don't use plus/minus grading. Your course syllabus is always the final word on which one applies to you.
Most percentage-to-GPA questions come from high school students in honors or AP classes, where the same percentage is worth more on a weighted scale. The table uses the 93/90/87 breakpoints and the common weighting of +0.5 for honors and +1.0 for AP or IB. Some schools give no weighting bonus for a D or F — the University of California, for example, adds no extra point for those grades — so those rows show none.
| Percent | Letter · GPA | Honors | AP / IB |
|---|---|---|---|
| 93–100 | A · 4.0 | 4.5 | 5.0 |
| 90–92 | A− · 3.7 | 4.2 | 4.7 |
| 87–89 | B+ · 3.3 | 3.8 | 4.3 |
| 83–86 | B · 3.0 | 3.5 | 4.0 |
| 80–82 | B− · 2.7 | 3.2 | 3.7 |
| 77–79 | C+ · 2.3 | 2.8 | 3.3 |
| 73–76 | C · 2.0 | 2.5 | 3.0 |
| 70–72 | C− · 1.7 | 2.2 | 2.7 |
| 67–69 | D+ · 1.3 | — | — |
| 63–66 | D · 1.0 | — | — |
| 60–62 | D− · 0.7 | — | — |
| Below 60 | F · 0.0 | — | — |
Two examples from real questions: an 89 in an AP class is a B+, which is 3.3 unweighted and 4.3 weighted. A 90 average across all honors or AP classes is an A−: 3.7 unweighted, 4.2 if the classes are honors, or 4.7 if they are AP. At a school using the 90/80/70 scale, that same 90 would be a full A — 4.0 unweighted, 5.0 in an AP class. A 60% is a D− (0.7) on the 93/90 scale and a D (1.0) on the 90/80/70 scale; anything below 60 is an F at both.
Many countries and some US graduate programs report GPA on scales other than 4.0 — commonly 5.0, 7.0, 9.0, 10.0, or a straight 100-point average. A simple way to approximate these on a 4.0 scale is proportional scaling: divide your GPA by its maximum possible value, then multiply by 4.0.
| Original scale | Formula | Example |
|---|---|---|
| 5.0 scale | GPA ÷ 5 × 4.0 | 4.2 → 3.36 |
| 7.0 scale | GPA ÷ 7 × 4.0 | 5.7 → 3.26 |
| 9.0 scale | GPA ÷ 9 × 4.0 | 7.2 → 3.2 |
| 10.0 scale | GPA ÷ 10 × 4.0 | 8.2 → 3.28 |
| 100-point scale | Score ÷ 100 × 4.0 | 85 → 3.4 |
This proportional formula is a widely used approximation, but it isn't universal — some US graduate schools and credential evaluation services (like WES or ECE) apply their own conversion tables rather than a straight proportional scale, especially for international transcripts. If you're submitting a GPA for a specific application (graduate school, transfer, employer), check whether that institution requires an official credential evaluation rather than a self-calculated conversion.
Searches like "90 to GPA" or "87 to GPA" are common because the honest answer is "it depends on your school's breakpoints" rather than a single fixed number. A 90% is an A− (3.7) under the 93/90/87 scale, but a straight A (4.0) under schools that set their A cutoff at 90 instead of 93. Both are correct depending on which convention your school uses — which is exactly why this tool lets you toggle between the two most common conventions rather than assuming one is universally right.

What is an 89 in an AP class as a GPA? On the 93/90/87 scale an 89 is a B+, worth 3.3 unweighted and 4.3 on a weighted scale that adds 1.0 for AP. On a 90/80/70 scale it's a B: 3.0 unweighted, 4.0 weighted.
What is 60% as a GPA? A 60 is a D− (0.7) on the 93/90 scale and a D (1.0) on the 90/80/70 scale. Below 60 is an F (0.0) on both, and many schools add no honors or AP bonus to a D or F.
What is 90 in GPA? Under the standard US breakpoints, a 90% typically converts to an A− (3.7 GPA). Under the alternate 90/80/70/60 breakpoint scale used by some schools, 90% would be the bottom of the A range (4.0). Check your syllabus to see which breakpoint scale your class uses.
What is 87 as a GPA? Under the standard breakpoint scale, 87% typically converts to a B+ (3.3 GPA). Under the alternate scale, 87% falls in the B range (3.0).
How do I convert a 10-point or 9-point GPA scale to 4.0? Use the formula: (your GPA ÷ your scale's maximum) × 4.0. For example, a 7.25 on a 10-point scale converts to (7.25 ÷ 10) × 4.0 = 2.9. This proportional method is a simple approximation; many schools and credential evaluators use their own conversion tables instead — check with the receiving school's admissions or registrar office for official conversions.
Is a 3.5 GPA the same as 87.5%? Not exactly. A 3.5 GPA doesn't map to a single percentage — it typically reflects a mix of grades (some A's, some B+'s) rather than one uniform score. If you're converting a single percentage grade, use the calculator above; if you're converting an already-averaged GPA, treat any percentage equivalent as an approximation only.
Why do my percentage and GPA not match what this tool shows? Percentage-to-letter breakpoints vary by school and even by individual instructor — some use 93/90/87/83 as A/A−/B+/B cutoffs, others use 90/80/70/60. This tool shows the two most common breakpoint conventions, but your actual syllabus grading scale is always the authoritative source for your specific class.
