Weighted to unweighted GPA, from your grades.
A weighted GPA number alone cannot be reversed. Enter your grades and the page recomputes the unweighted figure and the weighted one.
You cannot convert a weighted GPA to an unweighted one from the single number; you need the course grades. Unweighted GPA = total grade points (A=4, B=3, C=2, D=1, F=0) divided by the number of grades. A weighted GPA adds an extra point for honors-level courses. Schools weight differently, so this page follows the University of California method as the worked rule.

Why the number alone is not enough
A weighted GPA of 4.3 could come from many mixes of grades and honors courses. To get the unweighted figure you must remove the extra honors points, and that needs the list of courses, which grades they earned and which ones were weighted. The calculation is: take each letter grade as plain points, add them, and divide by the number of courses.
The UC rules this page follows
- Convert letter grades to points: A=4, B=3, C=2, D=1. Pluses and minuses do not count.
- Give an extra point for each semester of a UC honors-level course (AP, IB Higher Level, designated IB Standard Level, UC-transferable college courses, and UC-certified honors courses), with a maximum of 8 honors points between 10th and 11th grades.
- A grade of D or F in an honors course does not earn the extra point.
- Add up the points and divide by the number of letter grades earned. Do not round up or down.
UC counts a specific set of courses and years, so the number here is a way to check arithmetic, not your official UC GPA. UC calculates the official figure when you apply.
Worked example
Eight semester grades: A, A*, B, B*, C, A, B, A, with the asterisk marking two honors courses.
- Points: 4+4+3+3+2+4+3+4 = 27.
- Unweighted: 27 ÷ 8 = 3.375.
- Weighted (UC style): 2 honors points added, (27+2) ÷ 8 = 3.625.
The weighted figure is higher by 0.25, which is the honors points divided by the number of grades.

Frequently asked questions
Can I convert a weighted GPA to unweighted without my grades?
No. The extra points depend on which courses were weighted and what grade you earned in each, so the single number cannot be reversed.
How is unweighted GPA calculated?
Convert each letter grade to points (A=4, B=3, C=2, D=1, F=0), add them, and divide by the number of grades.
Do pluses and minuses count?
Not in the UC method. UC says pluses and minuses do not count; your school may use them differently.
Does a D or F in an honors course get the extra point?
No. UC grants the honors point only for grades of C or better.
Is this my official GPA?
No. Schools and colleges use their own scales, and UC calculates your official UC GPA from your application.
