GPA to Percentage Converter

Enter your GPA, pick the scale it is measured on, and the converter gives the percentage, the letter grade and the 10-point CGPA equivalent. The whole conversion takes seconds.

1. Enter your GPA, for example 3.5.
2. Pick your scale. Most US schools use the 4.0 scale. Weighted high school GPAs often use 5.0, and many universities outside the US use a 10.0 CGPA scale.
3. Leave the letter grade box ticked to see the US letter grade that matches the percentage.
4. Press Calculate, or press Enter. The percentage appears first and large, with the letter grade and the scale equivalents below.

The conversion is a straight proportion. Percentage = (GPA / scale maximum) x 100. On the 4.0 scale that reduces to GPA x 25, because 100 / 4 is 25. On a 5.0 scale it is GPA x 20, and on a 10.0 scale it is GPA x 10.

The formula treats the top of the scale as 100 percent and the bottom as zero. That is a reference conversion, not an official rule. US schools usually report the GPA alone and do not convert it, and no federal authority publishes a GPA to percentage table. Always check your own school or university table first. Our percentage to GPA converter runs the same math in reverse.

A student has a 3.5 GPA on a 4.0 scale. Convert it to a percentage and a letter grade.

1. Divide the GPA by the scale maximum. 3.5 / 4 = 0.875.
2. Multiply by 100. 0.875 x 100 = 87.5%.
3. Find the letter grade. 87.5 percent sits in the 87 to 89 band, so the letter grade is B+.
4. Find the 10-point CGPA equivalent. 3.5 / 4 x 10 = 8.75.

As a second check, a 3.0 GPA on the same scale gives 3.0 / 4 x 100 = 75%, a C. The same steps work on any scale, so try your own numbers in the tool above.

The scale changes everything. A 3.5 is 87.5 percent on a 4.0 scale, 70 percent on a 5.0 scale and 35 percent on a 10.0 scale. The GPA number alone means nothing until the scale is attached, so always state both when you report a GPA.

The 4.0 scale is the US standard. An A is 4.0, a B is 3.0 and a C is 2.0. The 5.0 scale is a weighted scale used by many US high schools, where honors courses add 0.5 and AP or IB courses add 1.0, so a strong student can pass 4.0. The 10.0 scale is the CGPA scale used in India, Pakistan and Bangladesh, where a 10.0 is the top mark. To convert a 10-point CGPA to a 4.0 GPA, multiply by 0.4. Our CGPA to percentage converter covers the 10-point scale in detail.

No single formula works everywhere, because grading rules differ by country, by university and often by department. Some Indian universities convert CGPA to percentage with CGPA x 9.5 instead of CGPA x 10. Some US schools award an A+ as 4.3 instead of capping the top grade at 4.0. Some use a plain A, B, C, D, F scale with no plus or minus grades at all.

Credential evaluators like WES go further and do not use a formula at all. They read the transcript course by course and take a credit weighted average, so no simple conversion reproduces their result. That is why the converter calls its answer an estimate. Use it for applications, resumes and quick comparisons, and use the official table from the receiving institution when one exists. Our GPA calculator builds a GPA from your courses and credit hours first, if you need the GPA itself.

Letter grades follow percentage bands. On the common US plus and minus scale, A runs from 93 to 100, A- from 90 to 92, B+ from 87 to 89, B from 83 to 86, B- from 80 to 82, C+ from 77 to 79, C from 73 to 76, C- from 70 to 72, D+ from 67 to 69, D from 63 to 66, D- from 60 to 62, and anything below 60 is an F. A 3.5 GPA at 87.5 percent is a B+, while a 3.0 at 75 percent is a C.

The bands are a convention, not a law. Your school may set A at 90 instead of 93, or skip plus and minus grades entirely. Check the grading policy on your transcript before you quote a letter grade. Our grade calculator works out a single course grade from weighted assignments and exams.
