How do my letter grades and percentages convert to a GPA on the 4.0 scale?
On the common indicative 4.0 scale, A+ or A (90 to 100 percent) equals 4.0, B+ or B (80 to 89 percent) equals 3.0, C+ or C (70 to 79 percent) equals 2.0, D (60 to 69 percent) equals 1.0, and F below 60 percent equals 0.0. Institutions vary.
On the common 4.0 scale, each letter grade and percentage band maps to an indicative GPA value, with A at 4.0 and F at 0.0. Conversions vary by institution, and grades such as B+ and C+ often differ.

My Advice
Use this table for a rough estimate only, since your target university may apply its own conversion. Check the university's grading guidance before you quote a converted GPA in your application.
