Grade Converter Tool | Percentage ↔ Letter ↔ GPA (4.0 / 5.0)

Why Use a Grade Converter Tool?

A **grade converter tool** takes the guesswork out of converting between different grading systems. You might ask yourself, “What GPA does 85% equal?” or “Is a B+ the same as a 3.3 GPA?” This tool provides instant answers, saving you time and avoiding mistakes.

It's especially useful for:

• **College applications:** Many U.S. universities ask for your GPA on a 4.0 scale, even if your school uses percentages or letters.
• **Scholarships:** Scholarship forms often require a GPA, not just a percentage.
• **Parents:** Who want to understand their child’s performance using a familiar grading system.
• **International students:** For standardizing grades for U.S. admissions.

Formulas Explained

The converter tool uses these standard conversion methods:

Percentage → Letter Grade: The tool compares your percentage to the cutoffs in the tables above. For example, an 85% falls in the 83-86% range, which converts to a B.

Letter → GPA: The tool looks up the corresponding GPA value based on the letter grade and the selected scale. For instance, a B on a 4.0 scale equals a **3.0 GPA**.

GPA → Percentage: The tool finds the letter grade equivalent for the GPA, then gives the midpoint of that letter grade's percentage range. For example, a 3.7 GPA is an A−, which has a percentage range of 90-92%, so the midpoint would be ~91%.

Worked Examples

Example 1: A student scores 92% in a class.

• Percentage → Letter: A−
• Letter → GPA (4.0 scale): 3.7

Example 2: A transcript shows a B+.

• Letter → Percentage: ~88%
• Letter → GPA (4.0 scale): 3.3

Example 3: A student has a GPA of 4.7 on a 5.0 weighted scale.

• GPA → Letter: A
• GPA → Percentage: ~94%

Useful FAQs

Q: What is the most accurate GPA scale?

A: The 4.0 scale is the most common in the U.S. The 4.33 scale is used by some colleges, and the 5.0 scale applies to weighted AP/Honors classes. There is no one "most accurate" scale, as it depends on the institution.

Q: Can GPA be higher than 4.0?

A: Yes. On weighted scales (like 5.0), an A in an AP or Honors course could be worth 5.0 instead of 4.0, which can result in a cumulative GPA above 4.0.

Q: How do I check my GPA?

A: The easiest way to check your GPA is through your school's student portal. You can also calculate it manually with a grade calculator or use our College GPA Calculator.

Q: How to work out a GPA from percentage?

A: Convert your percentage grade to a letter grade first, then use the corresponding grade point value from the tables above to find the GPA. This tool does that automatically for you.
