GPA to Percentage Calculator

Choose whether you have a GPA or a percentage, enter the value, and pick the scale. The answer is an estimate shown as a range, because there is no single official conversion formula.

What do you have?

Choose whether you are starting from a GPA or from a percentage. The value field and the result relabel and invert to match.

The GPA you want to convert. Must be between 0 and the scale maximum (4.0, 4.33, or 5.0).
The percentage you want to convert to a GPA (0-100).
The scale your GPA is on. It sets the proportional multiplier (4.0 → ×25, 4.33 → ×23.09, 5.0 → ×20) and the A+ cap. The 5.0 scale is a weighted high-school scale, so its conversion is especially rough.
