Conversion Formula

This calculator uses a proportional linear formula that maps the Philippine GWA scale (1.00 highest – 5.00 lowest) to the international 4.00 GPA scale:

GPA = 4.0 − ((GWA − 1.0) × 4.0 / (5.0 − 1.0))

A GWA of 1.00 converts to a GPA of 4.00 (highest), and a GWA of 5.00 converts to a GPA of 0.00 (lowest).
