About this grade converter
American transcripts mix three ways of describing the same performance: letter grades (A–F), percentages and 4.0-scale GPA points. This converter translates between all three in one click, using the standard conversion table shared by most U.S. high schools and colleges.
Pick a direction with the tabs above the input. Enter a test percentage to get the letter grade and the GPA points it is worth. Pick a letter grade to see the percent range it usually covers. Or type a GPA like 3.5 to see which letter it corresponds to.
The full chart below the tool doubles as a quick reference you can screenshot or bookmark — it is the same table counselors and registrar offices keep on hand when they evaluate transcripts.
How the conversion works
There is no formula — conversions follow a lookup table, because letter grades are categories, not numbers. Each letter owns a percent band (A is typically 93–96%, A– is 90–92%) and a fixed point value on the 4.0 scale (A = 4.0, A– = 3.7, B+ = 3.3 and so on). Your GPA is then the credit-weighted average of those point values.
Going from GPA points back to a letter uses the midpoint convention: anything from 3.85 to 4.0 reads as A, 3.5–3.84 as A–, and so forth. That is why a 3.5 GPA is usually described as "an A– average".

How to convert grades between formats
- Choose the conversion direction: Use the tabs: percent to letter, letter to percent, or GPA points to letter.
- Enter your value: Type the percentage or GPA points, or pick a letter grade from the list.
- Read all three formats: The result shows the converted value plus the remaining two formats, so you have the full picture for forms and applications.
Frequently asked questions
What is a 3.5 GPA in percentage?
A 3.5 GPA corresponds to an A– average, which sits in the 90–92% band on the standard conversion table. Schools sometimes describe it loosely as "about 90%", but the precise mapping depends on your institution's own letter-to-point scale.
Is an A+ worth 4.0 or 4.3?
At the large majority of U.S. high schools and colleges, A+ is capped at 4.0 — the plus is recognition, not extra points. A small number of schools use a 4.3 cap, mostly in Canada or in specific middle school scales. If your student handbook does not say otherwise, assume 4.0.
How do I convert my percentage grades for college applications?
U.S. applications expect letter grades and a 4.0-scale GPA. Find each percentage in the chart, note the letter, then average the point values weighted by credit hours. International students should usually report grades exactly as their school issues them and let the admissions office or a credential evaluator (WES, ECE) do the conversion.
Do all schools use the same conversion table?
No — the table on this page is the most common one, but cutoffs vary. Some schools start A at 90 instead of 93, some skip plus/minus grades entirely, and universities sometimes recompute every transcript on their own scale. Treat the chart as the national default and verify details in your school's handbook.
