How it works
The score-to-grade conversion is a simple two-step formula:
Percentage = (Score ÷ Maximum score) × 100
Letter grade & GPA = lookup against standard US scaleOnce you have the percentage, the calculator matches it to the same letter grade and GPA bands that most US schools use.
Example calculation
You score 47 out of 50 on a chemistry quiz. 47 ÷ 50 = 0.94, or 94%. On the standard scale, 94% is an A and worth 4.0 GPA points.

Frequently asked questions
How do I convert a score to a grade?
Divide your score by the maximum possible score, multiply by 100 to get a percentage, then match that percentage to the standard grading scale to get a letter grade and GPA.
What grade is 47 out of 50?
47 out of 50 is 94%, which is an A on the standard US scale and worth 4.0 GPA points.
Can I use this for any test or exam?
Yes — it works for quizzes, midterms, finals, lab reports, essays, or any assignment scored out of a maximum value. It does not matter whether the maximum is 10, 50, 75, 100, or any other number.
Does it work for UK or Indian grading?
The percentage works universally. The letter grade and GPA shown follow the US 4.0 scale, which is the most widely recognized international reference.
How is this different from a points calculator?
This converts a single score (one test, one assignment) into a percentage and grade. A points calculator sums earned and possible points across multiple assignments to find an overall grade.
What if my score is greater than the maximum?
That usually means extra credit. The calculator will still compute a percentage above 100%, but cap your interpretation at A / 4.0.
Is this calculator free?
Yes — fully free and works without signup on any device.
