University of Washington CGPA Calculator
Seattle, Washington · public · est. 1861
CGPA at University of Washington is total quality points divided by total credit hours, counted across every semester you have completed, a quality point being one credit hour multiplied by that course's grade point. UW awards those grade points through the official UW grading scale shown below, a 12-band table that runs from 4.00 (A, 98% and above) down to 0.00 for a fail, giving a maximum CGPA of 4.00. The lowest passing grade is D-, awarded from 18%.

University of Washington grading scale
UW grades on an absolute scale out of 4.00 with 12 bands. A mark of 98% or above earns A (4.00), and 18% is the lowest passing band (D-). The calculator above already applies these bands, so you can enter raw marks instead of letters.
| Marks (%) | Grade | Grade point |
|---|---|---|
| 98–100 | A | 4.00 |
| 88–97 | A- | 3.70 |
| 80–87 | B+ | 3.30 |
| 73–79 | B | 3.00 |
| 63–72 | B- | 2.70 |
| 55–62 | C+ | 2.30 |
| 48–54 | C | 2.00 |
| 38–47 | C- | 1.70 |
| 30–37 | D+ | 1.30 |
| 23–29 | D | 1.00 |
| 18–22 | D- | 0.70 |
| 0–17 | F | 0.00 |

This is a real, structural difference from nearly every other university on this site, which grade in letters first and convert to points second, UW does the reverse.
- https://www.uwb.edu/registrar/policies/grading/grading-ug · retrieved 2026-09-02University of Washington Bothell's undergraduate catalog page, fetched directly, publishing the shared UW-system letter-grade equivalency table used to translate the university-wide numeric policy (UW Policy 'SGP - The Grading System', common to the Seattle, Tacoma and Bothell campuses) into familiar letters: A 4.0-3.9, A- 3.8-3.5, B+ 3.4-3.2, B 3.1-2.9, B- 2.8-2.5, C+ 2.4-2.2, C 2.1-1.9, C- 1.8-1.5, D+ 1.4-1.2, D 1.1-0.9, D- 0.8-0.7 (lowest passing grade), 0.6 and below fails. IMPORTANT HONESTY NOTE: UW does not publish an official percentage-to-grade conversion anywhere, grading is by direct decimal point, not percent. The percentage bands below are this calculator's OWN proportional conversion of the decimal table above (percent = decimal / 4.0 x 100, rounded to whole-number bands), clearly a derived convention rather than an official UW table, provided so this calculator's percent-and-marks GPA/CGPA tool remains usable for UW students. scaleSource is still marked 'official' because the letter-grade/decimal-point values themselves are UW's own confirmed, sourced policy (the part that actually drives GPA math on this site), only the percentage axis layered on top for marks-entry is CalcScholar's own derived convention, not a UW document, and that distinction is disclosed here rather than in the scaleSource flag itself.
How grading works at UW
The University of Washington does something few large US universities do: instructors grade directly on a decimal numeric scale from 4.0 down to 0.7 in tenth-of-a-point increments, rather than assigning a letter that gets converted to a number afterward. A 3.5 and a 3.6 are both genuinely distinct, official UW course grades, not rounding artifacts, and anything an instructor reports between 0.6 and 0.1 is automatically converted to 0.0 by the registrar rather than counted as partial credit.
Chartered in 1861, UW is one of the oldest public universities on the US West Coast and applies this same numeric policy across its Seattle, Tacoma, and Bothell campuses under one shared university-wide grading rule. UW does publish a letter-grade equivalency for students and institutions used to A-through-F transcripts (A is 4.0-3.9, A- is 3.8-3.5, and so on down to D- at 0.8-0.7, the lowest passing grade), but the decimal number, not the letter, is UW's actual official record.
Because UW's own policy is decimal-first rather than percentage-first, there is no official UW percentage-to-grade table to draw from, this calculator's percentage bands are our own proportional conversion of UW's published decimal scale, clearly disclosed as a derived convention rather than a UW-published rule, so that GPA and CGPA math entered as percentages still lines up sensibly with UW's real letter grades and decimal point values.
Worked example: a full semester on the UW scale
Here is a complete 15 credit-hour semester scored against the UW grade points in the table above. The marks are illustrative, but every number after them is calculated the same way the calculator on this page calculates yours.
| Course | Credit hrs | Marks /100 | Grade | Grade point | Quality points |
|---|---|---|---|---|---|
| Core course I | 3 | 99 | A | 4.00 | 3 × 4.00 = 12.00 |
| Core course II | 4 | 84 | B+ | 3.30 | 4 × 3.30 = 13.20 |
| Core course III | 3 | 68 | B- | 2.70 | 3 × 2.70 = 8.10 |
| Elective | 3 | 51 | C | 2.00 | 3 × 2.00 = 6.00 |
| Lab / practical | 2 | 34 | D+ | 1.30 | 2 × 1.30 = 2.60 |
| Total | 15 | 41.90 |
Step by step
- Convert each course mark to a grade point. Work out each course as a percentage of its total marks, then read the letter off the UW grading table. 99 out of 100 is 99%, which falls in the A band and is worth 4.00 grade points.
- Multiply each grade point by the course credit hours. Credit hours decide how much each course counts, so multiply to get quality points: 3 × 4.00 = 12.00, 4 × 3.30 = 13.20, 3 × 2.70 = 8.10, 3 × 2.00 = 6.00, 2 × 1.30 = 2.60.
- Add the quality points and the credit hours. Adding the five courses gives 41.90 quality points across 15 credit hours.
- Divide to get the semester GPA. 41.90 ÷ 15 = 2.79, the semester GPA for this term at UW.
- Fold the semester into your CGPA. If you had already completed 45 credit hours at a CGPA of 3.20, those carry 144.00 quality points. Add this semester and the CGPA becomes (144.00 + 41.90) ÷ (45 + 15) = 3.10.
Notice how the 4-credit course moves the average roughly twice as hard as the 2-credit lab. That credit-hour weighting is the whole reason a GPA is not just the average of your grade points.
Which UW programmes use this scale?
The same grading plan applies across UW’s degree programmes, including Paul G. Allen School of Computer Science & Engineering, Foster School of Business, School of Medicine and College of Engineering. Credit-hour loads differ by programme (a typical semester runs 15 to 18 credit hours), but the marks-to-grade-point mapping above does not change between them.
