Convert a percentage to a GPA on the 4.0 scale, or a GPA back to a percentage. See both common methods side by side, so you know which number to use.
Type a number or tap a common value. Both conversion methods and the math appear here.
How to use the converter
- Choose Percentage to GPA or GPA to percentage.
- Type your number, or tap one of the common values.
- Keep the 4.0 (US) scale for American schools. Choose 5.0 or 10.0 if your school uses that scale.
- Read both answers. The letter grade method is how US schools build a GPA, and the simple formula is what many quick converters use.
Two ways to convert a percentage to a GPA
There is no single official formula. Schools and organizations use one of two approaches, and they give different answers.
1. The US letter grade method
US schools first turn a percentage into a letter grade, and the letter decides the grade points. On the plus/minus scale, 85% is a B (83 to 86.99%), and a B is worth 3.0. Every percentage from 83 to 86.99 gets the same 3.0.
This is the method behind a real US transcript GPA, so use it when you want to know what your GPA would be at an American school.
2. The simple formula
GPA = percentage ÷ 100 × 4 (the same as percentage ÷ 25)85 ÷ 25 = 3.40. It is quick and gives a different number for every percentage, but no US school calculates GPA this way. Some applications and converters use it, especially for students from other countries. For a 5.0 or 10.0 scale, multiply by 5 or 10 instead of 4.
Why the answers are different
At 85%, the letter method gives 3.0 and the simple formula gives 3.40. The letter method rounds every grade down to the start of its letter, while the simple formula keeps every point of the percentage. If an application tells you which method to use, use that one.
GPA to percentage
Going the other way, a letter grade covers a range, so a GPA matches a range of percentages, not one exact number. A 3.0 is a B, which covers 83 to 86.99% on the plus/minus scale. A 3.5 sits between B+ (3.3) and A− (3.7), so it matches roughly 87 to 92.99%. The simple formula multiplies by 25 instead: 3.5 × 25 = 87.5%.

Which method do colleges use?
US colleges use letter grades to build a GPA, so the letter method matches how they think. Many colleges also recalculate applicants’ GPAs their own way, and some application services publish their own conversion rules. If the college or service gives a method, use theirs.
My school uses a 10-point CGPA. Which formula should I use?
Use the official formula from your school, board or university if it publishes one. Many do, and their formulas differ. The 10.0 scale in this converter uses the simple formula, which is only a general estimate.
