Letter Grade To GPA: Formula and Example
This tool converts each letter to a “base GPA” (commonly out of 4.0), then scales it to your selected GPA maximum. It then averages across your entered courses.
Formula (simple average)
Scaled GPA per course = BaseGPA(letter) × (SelectedScale ÷ 4.0)
Overall GPA = (Sum of scaled GPAs) ÷ (Number of valid courses)
Example
If your scheme maps A = 4.0 and B+ = 3.3, and you choose a 5.0 scale:
- A → 4.0 × (5.0/4.0) = 5.00
- B+ → 3.3 × (5.0/4.0) = 4.125
- Average (2 courses) = (5.00 + 4.125) / 2 = 4.5625
