Letter Grades and GPA
Each letter has its own exact table points on every scale. B is 3.75 on 5.0 and 3.00 on 4.0; A− is 4.63 and 3.70, respectively.
GPA Scale Converter
Convert letter grades directly between the 5.0 GPA scale and your target scale
The source scale is fixed at 5.0. Select your target scale. Each letter maps directly to exact points on both scales; credits weight each GPA independently.

Per-Course GPA
Understand GPA Rules
Choose your source and target GPA scales, then enter each course’s letter grade and credits. Each letter maps directly to its exact reference-table points on both scales. Calculate each scale’s GPA independently using course credits.
GPA Credits
GPA credits are the credits attached to courses included in your calculation. A 4-credit course contributes twice as much as a 2-credit course.
Quality Points
Multiply each letter’s points by its course credits on each scale separately. Divide each scale’s total quality points by the same total credits.
This reference estimate uses the same letter grade on both scales. Schools may use different letter mappings or course bonuses; check institutional rules for an official conversion.
How to Convert a 5.0 Scale GPA to Your Target Scale
Select Your Target Scale
Your current GPA scale is fixed at 5.0. Choose a target of 4.0, 4.3, 5.0 or 10.0. The table supplies each letter’s points on both scales.
Add Grades and Credits
Enter credits and a letter grade for every course, then click Convert GPA. Review the GPA calculated from letter points independently on each scale.
Simulate Grade Changes
Open Simulator and change a course’s letter grade. Its source and target table points update, and credits weight the result on each scale. The original baseline stays fixed.
How GPA Scale Conversion Works on a 5.0 Scale
Look Up Each Course on Both Scales
Current course GPA = reference table[letter grade][source scale]
Converted course GPA = reference table[letter grade][target scale]
Converted course GPA = reference table[letter grade][target scale]
Read each letter’s points directly from the reference table. B is 3.75 on the 5.0 source scale and 3.00 on the 4.0 target scale. A− is 4.63 on the source scale and 3.70 on the target scale.
Calculate Quality Points on Each Scale
Current quality points = Σ (credits × source-scale letter points)
Target quality points = Σ (credits × target-scale letter points)
Target quality points = Σ (credits × target-scale letter points)
For B with 3 credits and A− with 4 credits, current quality points total 29.77 and target quality points total 23.80. Each scale uses its own exact letter points, including the listed two-decimal points on the 5.0 scale.
Find Your Overall GPA on Each Scale
Current GPA = current quality points ÷ total credits
Converted GPA = target quality points ÷ total credits
Converted GPA = target quality points ÷ total credits
Divide each quality-point total by 7 credits: current GPA is 4.25 on 5.0, and converted GPA is 3.40 on 4.0. Calculate from unrounded totals and round only the displayed values.
Letter Grade and GPA Scale Reference
Each column contains the exact reference-table points for the same letter grade on that scale. Read the source and target columns directly. A+ and A share the maximum on 4.0, 5.0 and 10.0; only A+ receives 4.30 on 4.3. The 5.0 column’s displayed two-decimal points are exact calculation inputs.
| Letter Grade | 5.0 Scale | 4.0 Scale | 4.3 Scale | 10.0 Scale |
|---|---|---|---|---|
| A+ | 5.00 | 4.00 | 4.30 | 10.00 |
| A | 5.00 | 4.00 | 4.00 | 10.00 |
