Percentage to Letter Grade Converter
Convert any percentage score to a letter grade on US, Canadian and Australian scales.
Teachers & Students| Scale | Grade | GPA points |
|---|---|---|
| US Plus/Minus | B | 3.0 / 4.0 |
| US Standard (90/80/70/60) | B | 3.0 / 4.0 |
| Canada | A | 4.0 / 4.0 |
| Australia (7.0 scale) | HD | 7.0 / 7.0 |
A percentage only means something once it is matched to a grading scale, and the same percentage means different things in different countries. Enter any score and this converter shows the result on the US plus/minus scale, the US standard scale, the Canadian scale and the Australian band scale at the same time, so a student comparing offers from universities in different countries can read one score four ways.
How to use the Percentage to Letter Grade Converter
- Enter the percentage score.
- Optionally choose one scale to highlight.
- Read the letter grade and GPA points on each of the four scales.
- Check the reference table below for the band boundaries around your score.
Formula
For example, on the US plus/minus scale the B band is 83-86%. A score of 85% falls inside it, so the letter grade is B and the GPA value is 3.0.
Worked example
A score of 85% converts to a B (3.0) on the US plus/minus scale, an A (4.0) on the Canadian scale where the A band starts at 85%, and a High Distinction (7.0) in Australia, where HD also starts at 85%. One percentage, three different transcripts, which is exactly why converters exist.
Good to know
Boundary scores cause the most confusion. An 89% is a B+ in the US plus/minus system but an A in Canada, and a 79% sits at the top of the US C+ band yet inside the Australian Distinction band. Universities that receive international applications do not convert with a single public table; services such as WES apply country-specific equivalencies. Treat this converter as the standard reference, and confirm high-stakes conversions with the receiving institution.
US grading scale reference
The table below is the US plus/minus scale used across this site. Where this tool offers other scales, the Canadian scale sets an A from 85% with a pass at 50%, and the Australian scale uses the bands HD (85%+), D (75-84%), C (65-74%), P (50-64%) and F (below 50%) on a 7.0 GPA.
| Letter grade | Percentage | GPA points |
|---|---|---|
| A+ | 97–100% | 4.0 |
| A | 93–96% | 4.0 |
| A- | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B- | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C- | 70–72% | 1.7 |
| D+ | 67–69% | 1.3 |
| D | 63–66% | 1.0 |
| D- | 60–62% | 0.7 |
| F | 0–59% | 0.0 |
Frequently asked questions
What letter grade is 85%?
In the US it is a B on both the standard and plus/minus scales. In Canada 85% is an A, and in Australia it is a High Distinction, the top band.
What percentage do I need for an A?
In the US, 90% on the standard scale or 93% for a plain A on the plus/minus scale. Canada sets A at 85% at many universities, and Australia sets its top band, HD, at 85%.
Is 70% a C or a D?
In the US, 70% is the bottom of the C- band on the plus/minus scale and a C on the standard scale. In Australia 70% is a Credit, and in Canada it is a B- at many universities.
Why do schools use different scales?
Scales grew out of national examination traditions. The US settled on 60% as a pass in most districts, while Canada and Australia set the pass at 50%, which shifts every band above it.
Can I convert a letter grade back to a percentage?
A letter covers a range, so the reverse conversion gives the band, not one number. The Letter Grade to GPA Converter shows the percentage range for each letter.
