JHU uses a plus/minus 4.0 scale. A+ and A both count as 4.0 — the GPA is never above 4.0.

The Math

How JHU GPA Is Calculated

JHU multiplies each grade's quality-point value by the course's credits, sums the quality points, then divides by total credits.

JHU GPA Formula
\[ \text{GPA} = \frac{\displaystyle\sum \text{Quality Points}}{\displaystyle\sum \text{Credits}} = \frac{\displaystyle\sum (\text{Quality Point} \times \text{Credits})}{\displaystyle\sum \text{Credits}} \]
Quality PointsGrade point value × credits for each course
CreditsTotal graded credits (excludes S, U, W, AU, I)

📝 Worked Example

A three-course example using the JHU quality-point scale:

CourseCreditsGradeQuality PointQuality Points
Calculus I4.0A4.004 × 4.00 = 16.00
General Chemistry3.0B+3.303 × 3.30 = 9.90
Expository Writing3.0C−1.703 × 1.70 = 5.10
Total10.031.00

Plugging into the formula:

\[ \text{GPA} = \frac{31.00}{10.0} = \mathbf{3.10} \]
Tool 2

JHU GPA to Percentage Converter

Convert your 4.0-scale JHU GPA to an equivalent percentage instantly.

Convert GPA → Percentage

Enter any JHU GPA between 0.0 and 4.0.

The Conversion Formula

JHU uses a 4.0 scale, so:

\[ \text{Percentage} = \text{GPA} \times 25 \quad \text{or equivalently} \quad \text{Percentage} = \left(\frac{\text{GPA}}{4.0}\right) \times 100 \]

Example: If your GPA is 3.5, then Percentage = 3.5 × 25 = 87.50%.

📌 Grades Excluded from GPA

The following marks carry no quality points and are not counted in the GPA computation: S (Satisfactory), U (Unsatisfactory), W (Withdrawal), AU (Audit), and I (Incomplete).

Under the S/U option, a grade of C− or above earns Satisfactory credit (S); a grade below C− is recorded as Unsatisfactory (U). Neither affects your GPA. When a course is repeated, the most recent grade replaces the earlier one in the GPA, though both remain on the transcript.

JHU GPA — Frequently Asked Questions

What GPA scale does Johns Hopkins University use?

JHU uses a plus/minus 4.0 quality-point scale: A+ = 4.0, A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D+ = 1.3, D = 1.0, and F = 0.0. Quality points are multiplied by credits to compute the GPA.

Is A+ worth more than 4.0 at JHU?

No. At Johns Hopkins, an A+ carries 4.0 quality points, identical to an A. JHU does not award 4.33 for an A+, so a JHU GPA can never exceed 4.0.

Do S and U grades affect my JHU GPA?

No. Satisfactory (S) and Unsatisfactory (U) grades carry no quality points and are excluded from the GPA computation. Under the S/U option, a grade of C− or above earns an S; below C− is recorded as U.

How do I convert my JHU GPA to a percentage?

Use Percentage = GPA × 25 (equivalent to (GPA ÷ 4.0) × 100). For example, a GPA of 3.5 converts to 87.5%.

What happens to my GPA when I repeat a JHU course?

When a course is repeated, the most recent grade replaces the earlier grade in the GPA calculation. Both attempts remain visible on the transcript, but only the latest counts toward the GPA.
