Write down your original GPA that uses the 4.0 scale. For example, you may have a GPA of 3.2.
Find your GPA on a GPA conversion chart. Many institutions convert GPA scores differently; so locate the appropriate GPA-conversion chart.
Match your GPA on a 4 point scale with the corresponding 100 point scale number. For example, using the chart at the Cascadia College website, a 3.2 GPA corresponds with an 87 out of 100.
