Free, and no account is needed. The conversion happens instantly in your browser.
Whole letters are the same on every 4.0 scale. The plus and minus values come in two common versions: tenths (3.7, 3.3, 2.7 ...) and thirds (3.67, 3.33, 2.67 ...). Some schools have no A+ or no D-, and a few give an A+ 4.33. Your registrar's catalog lists the values that apply to you.
Pass (P), withdrawn (W) and incomplete (I) grades usually carry no grade points and are left out of the GPA.
A- in a 4-credit class, A- in a 3-credit class and B in a 3-credit class.
Tenths scale: 3.7 x 4 + 3.7 x 3 + 3.0 x 3 = 34.9 grade points over 10 credits = 3.49.
Thirds scale: 3.67 x 4 + 3.67 x 3 + 3.0 x 3 = 34.69 over 10 credits = 3.47. Same grades, a slightly different GPA, which is why it matters which scale your school uses.
3.7 at most schools, or 3.67 at schools that use thirds for plus and minus grades.
3.3, or 3.33 on the thirds scale. A B is 3.0 and a B- is 2.7 (or 2.67).
At most schools an A+ counts as 4.0, the same as an A. Some colleges give it 4.33. Check your registrar's grading policy.
Convert each letter to grade points, multiply by the class's credits, add those up and divide by the total credits. Pass/fail and withdrawn classes are usually left out.
Usually the plus/minus scale: 3.7 vs 3.67 for an A-, or 4.0 vs 4.33 for an A+. Pick the scale your school uses.
