This Canada grades to GPA calculator converts Canadian marks to the US 4.0 scale across every grading system in the country — percentage, the 4.0, 4.3 and 4.33 scales, the York 9-point, the McMaster and Carleton 12-point, the Ottawa 10-point and the Manitoba 4.5. Crucially, it converts by letter grade rather than by division: dividing an 11 out of 12 by its maximum gives 3.67, but an 11 is an A, and an A is a 4.0. That shortcut costs students up to 0.44 grade points, and every competing calculator uses it. Convert course by course with credits, convert Ontario, BC or Alberta high school marks, or run it in reverse.

This calculator applies published conversion methods and shows the spread between them. It is an estimate for planning, not a credential evaluation — the GPA of record is the one your target university or its chosen NACES-member evaluator produces. Everything runs in your browser; no transcript data is uploaded.
How to Use the Canada Grades to GPA Calculator
Canada has no national grading standard, so the first step is finding out which system you’re actually on. Everything after that is straightforward.
- Find your scale on the transcript legend. Every Canadian transcript prints its grading scale, usually at the top of page one or in a legend at the bottom. Look for the maximum grade point value — 4.0, 4.3, 4.33, 4.5, 9, 10 or 12 — or the note that the institution reports percentages only. Do this rather than trusting any website’s list of universities, including the reference table further down this page: scales change, and the lists circulating online openly contradict each other.
- Select that scale in the calculator. The grade dropdowns rebuild to match. This matters more than it sounds: the York 9-point scale has no minus grades at all, so a converter offering you A− options isn’t modelling your transcript.
- Choose what you’re converting. Course by course if you have a transcript with credits — most accurate, and the method evaluators use. Overall GPA if you just have a single cumulative figure. Percentage if your university reports marks only, as Waterloo, Western and Saskatchewan do. High school for Ontario, BC, Alberta and other provincial Grade 12 marks. US GPA → CA if you’re coming the other way.
- Get your credits right. Canadian half-year courses are usually 0.5 credits, full-year courses 1.0 — but many universities report the same courses as 3 and 6 credit hours. Either convention works; mixing them in one calculation does not. The toggle button switches all rows at once.
- Leave the method on letter-anchored. Switch to linear division once to see what it costs you, then switch back. On a 12-point scale the gap is a third of a grade point; on the 9-point scale it’s closer to half.
- Read the range and the Canadian equivalent. The gold box shows the spread across all three methods; the third box confirms the letter grade and percentage band your input corresponds to, which is a useful check that you picked the right scale.
- Report the scale alongside the number. Put the converted 4.0 figure in the GPA field and your original GPA with its maximum in the nearest text box. There’s a full section below on the wording — this is where Canadian applicants lose the most ground for no reason.
Why Dividing Your GPA by Its Maximum Understates You
Every calculator that handles Canada’s non-standard scales does the same thing: divide by the maximum and multiply by four. It’s intuitive, it’s wrong, and it’s expensive.
The problem is that Canadian point scales aren’t stretched versions of the 4.0 scale — they’re letter scales with more room at the top. On a 12-point scale, 12 is A+, 11 is A, 10 is A−, 9 is B+. An 11.0 average is not “91.7% of the way to perfect,” it’s an A, and an A is a 4.0 everywhere. Compare what the two approaches produce:
| Your GPA | Scale | What it actually is | Letter-anchored | Linear division | You lose |
|---|---|---|---|---|---|
| 8.0 | 9-point (York) | A average | 4.00 | 3.56 | 0.44 |
| 11.0 | 12-point (McMaster) | A average | 4.00 | 3.67 | 0.33 |
| 9.0 | 10-point (Ottawa) | A average | 4.00 | 3.60 | 0.40 |
| 10.0 | 12-point | A− average | 3.70 | 3.33 | 0.37 |
| 4.0 | 4.5 scale (Manitoba) | A average | 4.00 | 3.56 | 0.44 |
| 3.9 | 4.33 scale (UBC, SFU) | A / A+ average | 3.90 | 3.60 | 0.30 |
| 3.7 | 4.0 scale (UofT, McGill) | A− average | 3.70 | 3.70 | none |
Read the last row and the pattern is clear: the shortcut only works if you’re already on a 4.0 scale. Everyone else pays for it — and the students who pay most are at York, McMaster, Carleton, Ottawa and Manitoba, precisely the students whose scales are least familiar to a US admissions reader.
The one case where it works in reverse
There’s a mirror-image trap on the 4.3 and 4.33 scales. Those aren’t stretched 4.0 scales either — the extra range sits entirely above the A anchor. A+ is 4.33, but A is still 4.0, A− is still 3.67, B+ is still 3.33. So a 3.9 out of 4.33 is roughly a 3.9 out of 4.0, and dividing by 4.33 costs you 0.30 for no reason. If you’re at UBC, SFU, Queen’s, Dalhousie or another 4.33 institution, your GPA is closer to a US GPA than any conversion formula suggests — just state the maximum so nobody assumes otherwise.
Canadian University GPA Scales — 4.0, 4.3, 4.33, 4.5, 9-Point, 10-Point and 12-Point
Unlike the UK’s degree classifications or Australia’s HD/D/C/P, Canada has no national convention at all. Education is provincial, and within each province individual universities set their own scales. Here is how the common ones line up against the same letter grades:
| Letter | Typical % | 4.0 | 4.3 | 4.33 | 9-pt | 10-pt | 12-pt | US GPA |
|---|---|---|---|---|---|---|---|---|
| A+ | 90–100 | 4.0 | 4.3 | 4.33 | 9 | 10 | 12 | 4.0 |
| A | 85–89 | 4.0 | 4.0 | 4.0 | 8 | 9 | 11 | 4.0 |
| A− | 80–84 | 3.7 | 3.7 | 3.67 | — | 8 | 10 | 3.7 |
| B+ | 77–79 | 3.3 | 3.3 | 3.33 | 7 | 7 | 9 | 3.3 |
| B | 73–76 | 3.0 | 3.0 | 3.0 | 6 | 6 | 8 | 3.0 |
| B− | 70–72 | 2.7 | 2.7 | 2.67 | — | 5 | 7 | 2.7 |
| C+ | 67–69 | 2.3 | 2.3 | 2.33 | 5 | 4 | 6 | 2.3 |
| C | 63–66 | 2.0 | 2.0 | 2.0 | 4 | 3 | 5 | 2.0 |
| D | 53–56 | 1.0 | 1.0 | 1.0 | 2 | 1 | 2 | 1.0 |
| F | Below 50 | 0 | 0 | 0 | 0 | 0 | 0 | 0.0 |
Two things worth noticing. First, the far-right column is identical down every row — that’s the whole point of letter-anchored conversion, and it’s why the maximum on your scale is irrelevant to the answer. Second, the 9-point scale has gaps: York’s scale runs A+, A, B+, B, C+, C, D+, D, E, F with no minus grades whatsoever, so there’s simply nothing to put in the A− and B− rows.
Which universities use which scale
| Scale | Commonly reported at | Note |
|---|---|---|
| 4.0 | University of Toronto, McGill, Alberta, Calgary, Saskatchewan | A+ and A both count 4.0 |
| 4.3 / 4.33 | UBC, Simon Fraser, Queen’s, Dalhousie, Concordia, Montréal | Extra range sits above the A anchor |
| 9-point | York University, University of Victoria | No minus grades on the scale |
| 10-point | University of Ottawa | Bilingual transcripts; also reported as letters |
| 12-point | McMaster, Carleton, Memorial | 12 = A+, 11 = A, 10 = A− |
| 4.5 | University of Manitoba | A+ = 4.5, A = 4.0 |
| Percentage only | Waterloo, Western, Windsor, Saskatchewan | No GPA printed on the transcript |
Course-by-Course Conversion — How Credential Evaluators Calculate Your US GPA
A course-by-course evaluation converts every course to US grade points, weights each by its credit value and averages. Same arithmetic as a US cumulative GPA:
Here is a realistic Canadian year, five half-courses and one full-year course, on a 12-point scale:
| Course | 12-pt grade | Letter | Credits | US points | Points × credits |
|---|---|---|---|---|---|
| Organic Chemistry | 11 | A | 0.5 | 4.0 | 2.00 |
| Calculus II | 10 | A− | 0.5 | 3.7 | 1.85 |
| Cell Biology | 12 | A+ | 0.5 | 4.0 | 2.00 |
| Statistics | 9 | B+ | 0.5 | 3.3 | 1.65 |
| Psychology | 8 | B | 0.5 | 3.0 | 1.50 |
| Thesis Project | 11 | A | 1.0 | 4.0 | 4.00 |
| Total | – | – | 3.5 | – | 13.00 |
Course-level US GPA = 13.00 ÷ 3.5 = 3.71. Now the shortcuts. That transcript is a 10.29 on the 12-point scale, which linear division turns into 3.43 — well below the 3.5 line a lot of programmes publish, from a student whose real standing is an A− average. The difference isn’t interpretation; one method models the grades and the other models the arithmetic.
Canadian Percentage to US GPA — Close Enough to Be Dangerous
Canada is the closest of the major systems to American grading, and that’s exactly why it catches people. A UK First at 70% or an Australian HD at 85% is obviously not a US percentage. A Canadian 84% looks like it needs no translation — and it’s out by a full grade band.
| Canadian mark | Canadian letter | US GPA | Same number read on a US scale | Gap |
|---|---|---|---|---|
| 90–100% | A+ | 4.0 | A− to A | small |
| 85–89% | A | 4.0 | B to B+ | one band |
| 80–84% | A− | 3.7 | B− | one band |
| 77–79% | B+ | 3.3 | C+ | one band |
| 73–76% | B | 3.0 | C | one band |
| 70–72% | B− | 2.7 | C− | one band |
| 63–66% | C | 2.0 | D | one band |
The shift is consistent: roughly five to eight percentage points, or one letter band, across the whole range. That’s a real gap — an 85% Canadian A becomes a US B if translated literally — but it’s nothing like the twenty-five-point chasm between a UK First and a US A. Canadian marking is somewhat more conservative, not fundamentally differently scaled, and being accurate about that is more useful than dramatising it.
Ontario, BC, Alberta and Quebec High School Marks to US GPA
For US undergraduate applications, you’re converting Grade 12 subject marks. Most of Canada reports percentages, which makes this the simplest of the provincial conversions — with one significant exception in Quebec.
Ontario, BC, Alberta and the percentage provinces
Ontario reports Grade 12 U (university preparation) and M (university/college) courses as percentages, and BC, Alberta, Manitoba, Saskatchewan and the Atlantic provinces work similarly. Convert each course individually against the Canadian bands — 90–100% and 85–89% both to 4.0, 80–84% to 3.7, 77–79% to 3.3, 73–76% to 3.0 — then average.
- Canadian high schools rarely weight courses, so a straight unweighted average is normally correct. There’s no direct equivalent of the US AP boost, though AP and IB courses taken in Canada are recognised on their own terms.
- Use your top six Grade 12 U/M courses if you’re presenting an Ontario average, since that’s the set Ontario universities use and it’s the figure your school will confirm.
- Include your school’s grading policy. A US reader seeing 82% may assume a B− unless told that in Ontario it’s a solid A−. One sentence in the additional-information box handles it.
- Provincial exams, where they still apply, are usually already blended into the reported mark — say so if your transcript separates them.
Quebec — CEGEP and the R-score
What to do instead: convert your individual CEGEP course marks, which are reported as percentages on the same scale as the rest of Canada, and report the R-score separately with a line explaining what it measures. US admissions officers find a cohort-adjusted rank genuinely useful once they know what it is — they simply can’t put it in a GPA field. It’s also worth noting that CEGEP is a two-year pre-university programme with no US equivalent, so a brief explanation of the structure helps more than it costs.
Canadian Credits to US Credit Hours
Canadian transcripts report course weight in one of two conventions, and both appear across the country:
| Course length | Decimal credit convention | Credit hour convention | US semester hours |
|---|---|---|---|
| Half-year (one term) | 0.5 credits | 3 credit hours | 3 |
| Full-year (two terms) | 1.0 credit | 6 credit hours | 6 |
| Standard full-time year | 5.0 credits | 30 credit hours | 30 |
| Three-year degree | 15.0 credits | 90 credit hours | 90 |
| Four-year honours degree | 20.0 credits | 120 credit hours | 120 |
A four-year Canadian honours degree at 20.0 credits maps cleanly to the 120 semester hours a US bachelor’s degree typically requires, which is one reason Canadian transcripts give US evaluators very little trouble. The practical rule is internal consistency: pick whichever convention your transcript uses and apply it to every row. Mixing 0.5-credit entries with 3-credit-hour entries in the same calculation weights the credit-hour courses six times too heavily, and the error is invisible in the output.
Which Canada to US GPA Conversion Method Should You Use?
There is no official conversion, and the three methods in circulation give materially different answers for anyone not already on a 4.0 scale:
| Letter | Letter-anchored | Linear division (12-pt) | Conservative | Spread |
|---|---|---|---|---|
| A+ | 4.0 | 4.00 | 4.0 | none |
| A | 4.0 | 3.67 | 3.9 | 0.33 |
| A− | 3.7 | 3.33 | 3.7 | 0.37 |
| B+ | 3.3 | 3.00 | 3.3 | 0.30 |
| B | 3.0 | 2.67 | 3.0 | 0.33 |
| C | 2.0 | 1.67 | 2.0 | 0.33 |
- Letter-anchored — converts your letter grade to its US equivalent, ignoring the maximum of your local scale. This is what a course-by-course evaluation does, and it’s the only method that gives the same answer regardless of which Canadian university you attended. Use this as your default.
- Linear division — divides by the scale maximum. Reasonable-sounding, universally repeated online, and systematically wrong for anyone not on a 4.0 scale. Useful only as a floor.
- Conservative — the letter-anchored mapping with A distinguished from A+ (3.9 rather than 4.0), which some US institutions apply to Canadian transcripts. Assume this one if a competitive programme says nothing about its method.
What to Write in the GPA Box on a US Application
Canadian applicants lose more ground here than anywhere else, because the number on their transcript looks like it belongs in the box. Three failure modes:
- Entering a 9-point, 10-point or 12-point GPA raw. An “11.0” in a field that caps at 4.0 is rejected as an error or, worse, silently truncated.
- Entering a 4.3 or 4.33 GPA without the maximum. A bare “4.1” reads as impossible on a 4.0 scale. A bare “3.9” reads as a 3.9/4.0 — which is roughly right, but only by luck.
- Entering a percentage average. An “82” in a GPA field is meaningless; an 82% read against a US scale is a B−, when in Canada it’s an A−.
The wording that works states the converted figure, the original figure with its maximum, and the scale — three facts, one line each:
Original: 10.29 / 12.0 — A− average, McMaster University
Scale: A+ 90–100% = 12, A 85–89% = 11, A− 80–84% = 10, B+ 77–79% = 9
- Always give the maximum. “3.9/4.33” costs you three characters and removes every ambiguity. “3.9” alone invites an assumption.
- Attach the transcript legend if the application accepts supporting documents. It’s the authoritative version of everything above, and it’s already printed on your transcript.
- Don’t round upward silently. If your range is 3.5–3.7, quote 3.6. An evaluator’s report that lands below your self-reported figure is a credibility problem you don’t need.
- If the form offers a scale dropdown, choose percentage and enter your average, or choose your actual scale if it’s listed. That sidesteps the conversion question altogether.
US GPA to Canadian Grades — the Reverse Conversion
American students applying to Canadian graduate programmes need the mirror image. Canadian universities usually publish requirements as a percentage or letter average over the final two years, not as a GPA:
| US GPA | Canadian % | Letter | 12-pt | Typical admissions read |
|---|---|---|---|---|
| 3.9 – 4.0 | 85–100 | A / A+ | 11 – 12 | Competitive for funding and research places |
| 3.6 – 3.8 | 80–84 | A− | 10 | Clears any published entry bar |
| 3.3 – 3.5 | 77–79 | B+ | 9 | The usual minimum for Canadian master’s entry |
| 3.0 – 3.2 | 73–76 | B | 8 | Meets a B-average requirement |
| 2.7 – 2.9 | 70–72 | B− | 7 | Borderline; some programmes accept with experience |
| Below 2.7 | Below 70 | C+ or lower | 6 or below | Below most published entry requirements |
Most Canadian master’s programmes ask for a B+ average (roughly 77%, about 3.3) in the final two years of the undergraduate degree — note the final two years, which is a genuine difference from the cumulative GPA most US programmes assess. If your first two years dragged your cumulative figure down, a Canadian application may read considerably better than a US one, and it’s worth calculating that final-two-years average separately before you apply.
