If your grades come back as percentages but every college resource talks in GPA, you need a translator. Enter any percentage below and this converter maps it to the standard US 4.0 scale — the same band-based method admissions offices use — along with the matching letter grade. Below the tool you'll find the full 100-point conversion chart and notes on why no single formula fits every school.
Instructions
Type any percentage grade from 0 to 100. The converter applies the standard US grade bands and shows the matching 4.0-scale GPA and letter grade instantly.

US transcripts don't convert percentages with arithmetic — they convert with bands. Your percentage first maps to a letter grade (an 88% is a B+, a 91% is an A−), and the letter grade then maps to fixed grade points on the 4.0 scale. That two-step lookup is why an 84% and an 86% both come out to exactly 3.0: both sit inside the B band.
You'll see a "linear" formula floating around the internet — (percentage ÷ 100) × 4 — and it's wrong for US transcripts. That formula would turn a 75% into a 3.0, when a 75% is actually a C worth 2.0 points. Band conversion is the standard, and it's what this calculator (and admissions offices) use.

Why Conversions Vary by School
The chart above is the most common US convention, but grading legends are set school by school. Districts that grade harder often stretch the bands, and a handful compress them.
Some schools set the A cutoff at 94% instead of 93%, and others award a B for anything at 85% or above. If your transcript's grading legend differs from the standard bands, the legend wins — it defines what your percentages officially mean.
International Grading Systems
Percentage bands elsewhere in the world carry different meanings, so they don't map 1:1 onto this chart. A 70% in the UK is first-class honours territory, an Indian 10-point CGPA compresses at the top, and Canadian provinces each draw their own percentage cutoffs. For US admissions, international applicants are usually asked to submit a credential evaluation from a service like WES rather than a self-converted GPA — see our GPA scale reference for how the major systems compare.
Frequently Asked Questions
An 85% falls in the B band (83–86%), which converts to a 3.0 on the 4.0 scale under the standard US conversion. A 3.0 is a solid GPA that keeps most four-year colleges in reach, though selective schools typically admit students averaging 3.7 or higher. Remember that your own school's grading legend may draw the B band slightly differently.
Not uniquely. Because whole bands of percentages map to a single GPA value, the conversion only runs one way — a 3.0 GPA could represent anything from 83% to 86%, and a 4.0 could be anywhere from 93% to 100%. If a form asks for a percentage and you only have a GPA, use the midpoint of the matching band or ask the institution which convention it wants.
Yes. US admissions offices routinely receive transcripts graded in percentages and convert them with their own internal tables, and for international transcripts most require a professional evaluation from a service like WES or ECE. You generally should not convert your own grades on an application unless the instructions explicitly ask you to.
Weighting doesn't change the percentage itself — it changes the grade points a course earns after conversion. An 88% in AP Chemistry and an 88% in regular chemistry are both a B+, but on a weighted scale the AP version earns 4.3 points (3.3 + 1.0) while the regular version earns 3.3. The rigor bump attaches to the course type, not the percent score.
There is no reliable arithmetic shortcut — the divide-by-2.5 formula that circulates online is not accepted by US institutions. A 10-point Indian CGPA reflects a different grading philosophy, so US universities require an official credential evaluation from a service such as WES, which considers your institution and grade distribution rather than applying a flat formula.
