US, Canada & Australia Grading Systems

An 85% is a B in one country, an A in a second and a High Distinction in a third. Grading systems are national conventions, not measurements, and anyone studying, applying or hiring across borders needs the translation. This guide compares the United States, Canada and Australia side by side: their scales, pass marks, GPA systems and the conversions that matter in practice.

The United States: letters on a 4.0 scale, pass at 60

American schools grade from A to F. On the standard scale an A begins at 90%, B at 80, C at 70 and D at 60, with F below 60; many institutions refine this with plus and minus grades, where a plain A starts at 93% and A- covers 90-92. Letters convert to grade points, A = 4.0 down to F = 0, and GPA is the credit-weighted average of those points.

The detail that surprises visitors is the pass mark: 60% (a D) is the lowest passing grade in most US districts and colleges, though a D often does not satisfy major or prerequisite requirements, where a C is the working minimum.

Canada: similar letters, lower lines, pass at 50

Canada uses the same A-to-F letters and a 4.0 GPA at most universities, but the percentage bands sit lower: an A is commonly 85-89%, an A+ 90-100%, a B in the 70s, and the pass mark is 50% rather than 60. Identical letters therefore do not mean identical marks: a Canadian transcript average of 82% is an A- record, while a US 82% is a B-.

Two further variations matter. Some Canadian universities use a 4.33 scale where an A+ is worth 4.33, and Ontario maintains its own provincial levels for school reporting plus the OMSAS conversion table for medical school applications. The Canada GPA Calculator handles both the 4.0 and 4.33 variants.

Australia: bands on a 7.0 scale, WAM alongside

Australian universities name their bands instead of lettering them: High Distinction (85%+, worth 7 points), Distinction (75-84, 6), Credit (65-74, 5), Pass (50-64, 4) and Fail (below 50, 0), producing a GPA on a 7.0 scale. The pass mark matches Canada at 50%. Boundaries vary slightly by university, with some setting High Distinction at 80%.

Australia also reports the WAM, the weighted average mark, which averages the raw percentages themselves. Because it preserves information that banding discards, Australian employers often set WAM cut-offs for graduate roles, and a student may be asked for either number. The WAM to GPA Converter explains the relationship between them.

Side by side

Read across for the same performance: a mark of 85% is a B (3.0) in the US plus/minus system, an A (4.0) in Canada, and a High Distinction (7.0) in Australia. A mark of 75% is a C (2.0) in the US, a B (3.0) in Canada, and a Distinction (6.0) in Australia. A mark of 55% fails in the US, passes as a D range mark in Canada, and is a Pass in Australia.

The pattern: the further the system is from the US, the more the numbers flatter the same work, which is exactly why raw percentages must never be compared across countries without conversion.

Converting properly for applications

For applications, convert through the bands, never by copying percentages into another country's table. A US admissions office reading an Australian transcript works from the HD/D/C/P bands; credential services such as WES publish country-specific equivalencies, and universities reserve the right to apply their own.

On this site, the Percentage to Letter Grade converter shows one score on all three systems at once, the Canada and Australia GPA calculators compute within their own rules, and the UK Grade to US GPA converter covers the fourth system students most often need, the British one, where 70% is the top band.

In short

Three systems, three meanings for the same number. Keep the pass marks (60 US, 50 Canada and Australia) and the top bands (A from 90 or 93 US, 85 Canada, HD from 85 Australia) in mind, convert through bands rather than raw percentages, and every transcript you meet will read clearly.
