Background

About the U.S. GPA System

4.0 Scale

Most U.S. universities use a 4.0 GPA scale where A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0. Many use plus/minus modifiers (A− = 3.67, B+ = 3.33), and some allow A+ to exceed 4.0 before capping the cumulative GPA.

Standard Formula

GPA = Σ(Grade Point × Credit Hours) ÷ Σ(Credit Hours). This credit-weighted average is used across all U.S. universities, though the letter-grade-to-grade-point mapping varies slightly between institutions.

Percentage Conversion

The standard 4.0-scale conversion is Percentage = GPA × 25, equivalent to (GPA ÷ 4.0) × 100. U.S. transcripts rarely show percentages — use this approximation only when an external institution requests it.

Latin Honors

Most U.S. universities award Latin honors at graduation — cum laude, magna cum laude, and summa cum laude — typically requiring a GPA of 3.5 or higher. Exact thresholds vary by institution and are often set by class rank percentile.

Got Questions?

U.S. GPA — Frequently Asked Questions

Why does my U.S. university show a different GPA scale?

While the 4.0 scale is the U.S. standard, the exact grade-point values differ between institutions. Some use plus/minus modifiers, some don't; some award A+ = 4.33 (capped at 4.0), and a few use unweighted vs. weighted GPAs.

For consistency, each university's calculator above uses the exact grade-point mapping published in that institution's official policy.

How do I convert my U.S. GPA to a percentage?

On the 4.0 scale, the standard conversion is Percentage = GPA × 25. Examples: GPA 3.5 → 87.5%, GPA 3.0 → 75%, GPA 2.0 → 50%.

U.S. universities don't usually print percentages on transcripts. Use the per-university calculators above for the exact formula recommended by each institution.

What's a "good" GPA in the USA?

On a 4.0 scale:

3.7+ (A−/A) — Excellent. Competitive for graduate school, scholarships, and top employers.
3.0–3.69 (B to A−) — Good. Eligible for most graduate programs.
2.0–2.99 (C to B−) — Satisfactory. Meets graduation requirements at most universities.
Below 2.0 — Academic probation possible at most institutions.

Professional programs (e.g., medical school, law school) have their own GPA cut-offs that may be much higher than the university minimum.

Are these calculators official?

No — CGPAPro is an independent third-party tool and not affiliated with any university. Each calculator uses the grading scale and conversion formula published in the respective university's official policy documents (linked in the References section on each page).

For your official transcript or conversion certificate, always contact the Office of the Registrar at your university.

Can I request my university to be added?

Yes! Use our contact form and tell us which U.S. university you'd like added. Include a link to the official grading policy if possible — that helps us build an accurate calculator faster.
