GPA to Percentage

What the GPA to Percentage Converter Does

The GPA to Percentage converter translates between grade point average and percentage scores in both directions. Enter a GPA to see the percentage equivalent and the matching letter grade, or enter a percentage to find the GPA it corresponds to. The tool supports the standard 4.0 unweighted scale and the 5.0 weighted scale used for honors and Advanced Placement courses, and it includes a full conversion table so you can compare nearby values at a glance.

Every result updates as you type, and the conversion runs entirely in your browser. Nothing is stored or sent anywhere.

How to Use the Converter

1. Pick the GPA scale: 4.0 for unweighted grades or 5.0 for weighted grades.
2. Choose the conversion direction: GPA to percentage, or percentage to GPA.
3. Type the value you want to convert.
4. Read the result card for the converted value and letter grade, then use the table for nearby reference points.

How the Conversion Works

The converter uses the standard band-based mapping most schools apply when they report both a GPA and a percentage. On the 4.0 scale, each whole GPA point lines up with the bottom of its letter grade band: 4.0 is about 93%, 3.0 is about 83%, 2.0 is about 73%, and 1.0 is about 63%. The formula is:

Percentage = (GPA x 10) + 53 on the 4.0 scale, and Percentage = (GPA x 10) + 50 on the 5.0 scale, where a 5.0 maps to 100%.

To convert the other way, subtract the same constant and divide by ten. For example, 88% becomes (88 - 53) / 10 = 3.5 on the 4.0 scale, which is a B+. Results are clamped to the valid range, so a percentage above the top of the scale caps at the maximum GPA and anything below the bottom caps at zero.

4.0 Scale Grades in Detail

The 4.0 scale is the most common unweighted system in the United States. An A is 4.0, a B is 3.0, a C is 2.0, a D is 1.0, and an F is 0. Pluses and minuses shift the value by roughly a third of a point, so an A- is 3.7 and a B+ is 3.3. The percentage equivalents follow the familiar letter bands: A is 93 to 96, A- is 90 to 92, B+ is 87 to 89, B is 83 to 86, and so on down to F below 60.

Weighted GPA and the 5.0 Scale

Weighted GPAs reward course difficulty. An honors or AP class can be worth a full extra point, so an A in an AP course may count as 5.0 instead of 4.0. This is why two students with the same letter grades can have different GPAs, and why a weighted 4.0 is not the same as an unweighted 4.0. When you enter a weighted GPA on this page, select the 5.0 scale so the percentage and letter grade reflect the right system.

Why Schools Convert Between GPA and Percentage

Many international universities ask for a percentage while US transcripts report a GPA. Scholarship applications sometimes set a minimum percentage, and some employers request a percentage on internship forms. The reverse also happens: a school that reports percentages on a 100 point scale may need a 4.0 GPA for a transfer application. Always check whether the receiving institution wants a weighted or unweighted value, because the same percentage maps to different GPAs on the two scales.
