What the Letter Grade Converter does
Letter Grade Converter: converts Letter grade and GPA points from Percentage score. Example: percentage score 85 gives letter grade B.
The Letter Grade Converter turns Percentage score into Letter grade and GPA points. There is no submit step; the numbers move as you adjust them.
It is mostly used by parents checking a report. Small weighting differences move a final grade more than people expect.
Nothing leaves the tab. You can watch your browser network panel while you use it and see for yourself.
Everything needed to verify a result is further down: the fields, the method and one fully worked example.
What do the Letter Grade Converter fields mean?
The Letter Grade Converter uses 1 input. Rather than an empty form you get a filled one, useful when you only want to test a single change.
| Field | What to enter | Default |
|---|---|---|
| Percentage score | accepts 0 to 100 | 85 |
How does the Letter Grade Converter work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same conversion.
Inputs are validated before anything is computed, so a bad entry is reported rather than quietly producing a wrong answer.
Worked example
These are the values the Letter Grade Converter loads by default, and the result it produces from them. The defaults produce the result shown here; change any of them and the answer moves.
| Percentage score | 85 |
|---|
| Letter grade | B |
|---|---|
| GPA points | 3.0 |
How to use it
- Key in Percentage score (0 to 100).

What this tool does not do
- Weightings vary by course, so confirm the rules your school actually applies.
- Grading scales differ between institutions; check your own before relying on a converted figure.
- The tool answers exactly the question it is given; it cannot know the context around your numbers.
- A number that passes validation has been checked for plausibility, not for correctness.
Frequently asked questions
One thing: Percentage score. A starting value is in place for each, so nothing is mandatory before you see a result.
Percentage score accepts 0 to 100. The range is enforced before the calculation runs, so a bad entry never reaches the formula.
With the values loaded when the page opens, letter grade comes out as B. Edit any input and that figure moves with it.
No record is kept. We never receive what you type, so there is nothing on our side to retain.
No cost and no account. Use it as often as you like.
It is exact within the stated method. Anything the method does not model is simply out of scope.
