Short answer. A 2.9 GPA is about 83% on the common US 4.0 scale. That is between a B- (2.7) and a B (3.0). Schools set their own bands, so check yours.
What a 2.9 GPA is in percent
With a 2.9, your grades are mostly in the B- and C+ range. It is a middle result on the 4.0 scale.
On the common US plus and minus scale, a 2.9 GPA falls between a B- (2.7) and a B (3.0). The B- band is 80% to 82% and the B band is 83% to 86%. A straight-line estimate between the middles of the two bands gives about 83%. The nearest single letter is B.
How other methods convert 2.9
There is no single official way to turn a GPA into a percentage. These are the methods you will see most often.
| Method | Result | Notes |
|---|---|---|
| Plus and minus scale (used on this site) | about 83% | The usual US bands, with a straight-line estimate between letters. |
| 10-point scale, no plus or minus | about 84% | A is 90 to 100, B is 80 to 89 and so on. Uses the middle of each band. |
| Simple proportion (GPA / 4 x 100) | 72.5% | Quick, but not a real grading scale. It runs low for most GPAs. |
The three methods give results from 72% to 84% for the same 2.9. That gap is large enough to matter on a form, so say which method you used. If a school or employer asks for a percentage, use the conversion your own school prints on its transcript or grading policy.
What grades give a 2.9
For example, 7 courses at B and 3 at B- (all with the same credits) average 2.91, which rounds to about 2.9. Credits change the weight of each course, so a 4-credit class moves the average more than a 1-credit class.
These figures assume an unweighted 2.9. If your 2.9 is a weighted GPA that includes honors or AP points, the unweighted number behind it is lower, and so is the percent. Convert the unweighted GPA when a form asks for a percentage.
Next steps
If a program you want lists a 3.0 minimum, work out the gap now. The GPA goal calculator gives the GPA you need over a set number of new credits.

Worked example
Example. Your transcript shows a 2.9 cumulative GPA and a form asks for a percent. On the plus and minus scale, write about 83%. If the form names a different scale, use that scale instead.
