How does percentage map to GPA?

It uses the common US table: 93–100% is 4.0 (A), 90–92% is 3.7 (A−), 83–86% is 3.0 (B), and so on down to below 60% which is 0.0 (F).

Is this the same everywhere?

No — some schools use slightly different cut-offs. This tool uses the widely cited College Board style table as a sensible default; check your institution's scale if it differs.

What GPA is a 90 percent?

A 90% falls in the 90–92 band, which maps to a 3.7 GPA and an A− letter grade on this standard scale.

What percentage do I need for a 4.0 GPA?

You need 93% or above for a 4.0 (A) on this table. Scores from 90 to 92% give a 3.7 (A−).

How do I convert a whole transcript to a cumulative GPA?

Convert each course percentage to its GPA point, then average those points — weighting by credit hours if your courses differ in size. This tool converts one grade at a time.

Is an A− worth 4.0 or 3.7?

On this unweighted 4.0 scale, a straight A (93–100%) is 4.0 and an A− (90–92%) is 3.7. Some weighted or honours scales treat them differently, so confirm your school's policy.

Q: Does this upload my grades?

No. The conversion happens entirely in your browser and nothing leaves your device.

Percentage to GPA

Enter a percentage grade and this tool converts it to a GPA on the 4.0 scale along with the matching letter grade. It is handy for students translating a course mark, comparing grades across systems, or estimating a GPA for applications that expect the US scale.

How it works

The converter clamps your input to 0–100, then finds the band it falls into and returns that band’s GPA point and letter:

Percentage	Letter	GPA
93–100	A	4.0
90–92	A−	3.7
87–89	B+	3.3
83–86	B	3.0
80–82	B−	2.7
77–79	C+	2.3
73–76	C	2.0
70–72	C−	1.7
67–69	D+	1.3
63–66	D	1.0
60–62	D−	0.7
Below 60	F	0.0

Example

A grade of 88% falls in the 87–89 band, which maps to B+ and a GPA of 3.3. A 95% maps to A / 4.0, and a 71% maps to C− / 1.7.

This is the widely cited College Board style table; some institutions use slightly different cut-offs, so check your own scale if it differs. The conversion happens entirely in your browser and nothing leaves your device.
