About this calculator

Convert between percentage and GPA on the 4.0, 5.0, or 10.0 grading scale — in either direction.

The 10.0 scale uses the common CBSE-style formula (GPA = Percentage ÷ 9.5). The 4.0 scale uses standard US letter-grade percentage bands to find the equivalent GPA, and the 5.0 scale scales those same 4.0 results proportionally by 1.25.

How to use

  1. Choose the conversion direction: Percentage to GPA, or GPA to Percentage.
  2. Choose your grading scale: 4.0, 5.0, or 10.0.
  3. Enter the value to convert.
  4. Press Calculate to see the converted value.

Formula

10.0 scale: GPA = Percentage ÷ 9.5 4.0 scale: GPA from standard percentage-to-letter-grade bands 5.0 scale: 4.0-scale GPA × 1.25
