GPA to Letter Grade Conversion Formula

The converter uses a simple normalization step:

Normalized Percentage (%) = (GPA ÷ GPA Scale) × 100

Then it maps that percentage to a letter grade using the selected scheme’s threshold table (for example, US A = 93%+ by default).

Example

If your GPA is 3.6 on a 4.0 scale:
Normalized % = (3.6 ÷ 4.0) × 100 = 90%
In the default US scheme, 90% typically maps to A-.
