GPA equivalent
4.00
Uses the standard US 4.0 scale - some schools use a slightly different exact cutoff or scale.

The standard 4.0 scale

A+ / A = 4.0 A- = 3.7 B+ = 3.3 B = 3.0 B- = 2.7 C+ = 2.3 C = 2.0 C- = 1.7 D+ = 1.3 D = 1.0 D- = 0.7 F = 0.0
Example

A 91% score converts to an A- letter grade, which equals 3.7 on the standard 4.0 GPA scale.

Step-by-step guide

  1. Choose whether you're converting from a letter grade or a percentage.
  2. Select or enter the grade.
  3. Read the GPA equivalent on the standard 4.0 scale.

Why some schools don't use plus/minus grades at all

Not every school uses the full plus/minus system shown here - some use only whole-letter grades (A, B, C, D, F), each worth a flat 4.0, 3.0, 2.0, 1.0, or 0.0 with no intermediate values. If your school doesn't use plus/minus grading, simply use the flat letter value instead of the +/- variant, since your actual transcript won't have those in-between grades to convert.

Common mistakes

Assuming every school uses identical percentage cutoffs for each letter grade - some schools use a slightly different scale (like 90-100 for a flat A, no A-/A+ distinction), so check your specific institution's grading policy.
Confusing a single grade's GPA equivalent with an overall GPA - a single course grade converts directly using this table, but an overall GPA needs credit-hour weighting across multiple courses, which our full GPA Calculator handles.

Frequently asked questions

Is A+ always worth more than A?

Usually not on the standard US 4.0 scale - most schools cap GPA at 4.0, so A+ and A both typically convert to the same 4.0 value, even though A+ reflects a higher percentage score. Some schools do give A+ a value above 4.0; check your school's specific policy.

How do I convert an international grade to US GPA?

International grading systems (UK degree classifications, European ECTS grades, and others) don't map directly onto the US 4.0 scale, and conversion methods vary by the receiving institution - check with the specific school or organization requesting the conversion for their preferred method.

Should I use this for a single grade or my overall GPA?

This tool is best for converting one grade at a time. For your overall GPA across multiple courses with different credit hours, use our full GPA Calculator instead.
