Percentage to Letter Grade

Q: What letter grade is 85%?

On the US +/− example scale, 85% is a B 3.0 . Without +/−, it is also a B. On the Canadian 4.33 example scale, it is an A 4.0 , which shows how much scales differ.

How to convert a percentage to a letter grade

Type your Score (% or points like 43/50). Points are turned into a percentage first: 43/50 = 86%.
Pick a Scale: US, A–F with +/− (example), US, A–F without +/− (example) or Canada, 4.33 scale (example).
Read the Letter grade, its GPA points, the Percentage used and the letter’s Range.

The result updates as you type. A score is compared with each letter’s minimum, and the highest letter whose minimum you reach is the one you get: with the US +/− scale, 89.99% is still a B+ and 90% is an A−.

Adapt the scale to your school

Grading scales are not universal. One school gives an A from 93%, another from 90%, and a Canadian university might start its A+ at 90% and give it 4.33 points. Under Edit the scale, every letter has a From (%) value (its minimum percentage) and a number of Points. Change any value, rename letters, use Add a letter for a new one or × to remove one. The scale menu then shows Custom (edited). Restore the example scale brings back the last example you picked.

A few rules keep a custom scale valid: each letter needs a unique name and a minimum of 0 or more. Rows that break these rules are highlighted and ignored. If no letter starts at 0%, scores below the lowest minimum get no letter, which is handy for pass/fail scales such as “Pass from 50%”.

Convert a whole list

Teachers and parents can convert many scores at once in Convert a list (one score per line). Each line can be a percentage or points, and the table shows the percentage, letter and points for each one. Blank lines are skipped and invalid lines are flagged in red.

Common US scale with +/−

Letter	Percentage	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	below 60	0.0

Ranges in the table are shown for whole numbers; the tool itself handles decimals, so 92.5% is an A−. Some schools give an A+ 4.33 points, and some don’t use A+ or D− at all.

Frequently asked questions

What letter grade is 85%?

On the US +/− example scale, 85% is a B (3.0). Without +/−, it is also a B. On the Canadian 4.33 example scale, it is an A (4.0), which shows how much scales differ.

Does the tool round my score?

No. It compares the exact value you type. Many teachers round to the nearest whole number before assigning a letter, so 89.5% may become a B+ or an A− depending on that policy.

Where do these scales come from?

They are common examples, not an official standard. US schools often use 10-point bands, and several Canadian universities use a 4.33 scale. Check your syllabus or student handbook for the scale that applies to you.

Can I convert letters back to percentages?

A letter covers a range, so it has no single percentage. The Range shown with each result tells you the span of percentages behind a letter.

Is anything sent or saved?

No. The conversion happens in your browser, and custom scales are not stored.
