How To Convert A GPA To A Percentage Calculator

A GPA only means anything once the scale is known, so conversion is a division by that scale.

Percentage of the scale

85.00%

Equivalent on the 4.0 scale
3.4

Values update as you type. This calculator covers the single scenario its formula assumes — see Common Mistakes for what it leaves out.

The formula this calculator uses

percentage = GPA / scale

GPA
Grade point average as reported by the school
scale
The top of the GPA scale, such as 4.0, 5.0 or 10.0
percentage
The GPA as a share of the scale maximum

How to check the result by hand

  1. 1

    Find the scale the GPA was reported on

    It is printed on the transcript or stated in the school handbook. If it is missing, ask, because assuming 4.0 for a 10 point scale is the single most damaging error in this conversion.

  2. 2

    Check whether the average is weighted

    A weighted average can exceed the nominal scale maximum. If it does, a plain linear conversion produces a figure above one hundred percent and is the wrong tool.

  3. 3

    Divide the GPA by the scale

    Eight point five over ten is 0.85. This is the share of the scale maximum that the average represents.

  4. 4

    Multiply by a hundred for a percentage

    0.85 is eighty five percent. Keep the precision of the source figure, so a 3.375 on a 4.0 scale stays at 84.375 percent rather than being rounded early.

  5. 5

    Optionally restate it on the 4.0 scale

    Multiply the share by four, so 0.85 becomes 3.4. This is the figure most international readers will recognise.
