5.0 Scale GPA Converter
Convert a GPA or grade from a 4.0, 4.3, 4.5, 7, 10, 20 or 100-point scale to the 5.0 scale, with 4.0 and 10-point equivalents and a table.
A request for a GPA out of 5 can mean different things. This tool only compares numeric positions within explicitly entered scales. This converter rescales a grade from any common scale, such as 4.0, 4.3, 4.5, 7, 10, 20 or a percentage, to its proportional equivalent out of 5.0, and shows the matching 4.0 and 10-point values. A conversion table lists the main steps of your scale so you can see where nearby grades land.
How to use this tool
- Enter your grade or GPA.
- Pick the scale it is on, or choose Custom and enter the top and bottom of your scale.
- Read the 5.0-scale value and the 4.0 and 10-point equivalents.
- Use the table to compare other grades on the same scale.
Formula
GPA₅ = (grade − scale minimum) ÷ (scale maximum − scale minimum) × 5
For scales that start at 0 this is simply grade ÷ maximum × 5. The same fraction times 4 or 10 gives the 4.0 and 10-point values, and times 100 gives the percent of the scale.
Example
A 3.6 GPA on a 4.0 scale is 3.6 ÷ 4.0 = 90% of the scale. Ninety percent of 5.0 is 4.50, so 3.6/4.0 corresponds to 4.5/5.0, and to 9.0 on a 10-point scale. Likewise a score of 80% becomes 4.0 out of 5, and a 4.0 on a 4.3 scale becomes 4.65.
Frequently asked questions
Is 4.5 on a 5.0 scale the same as 3.6 on a 4.0 scale?
Proportionally, yes: both are 90% of the top grade. Admissions offices may still recalculate your GPA from your transcript using their own rules.
How does a weighted 5.0 high-school GPA differ?
Some schools add course-difficulty bonuses, with amounts that depend on the course and school. Dividing a weighted GPA by 5 cannot remove those bonuses; rebuild the unweighted GPA from course grades instead.
Can I use a scale where a lower number is better?
No. This tool assumes that the largest number is the best grade. A reverse scale needs its own transformation, including the applicable pass threshold and institutional rules.
Does a proportional conversion work for every country?
No. Linear rescaling does not account for passing grades, grading distributions or course weighting. It is an arithmetic comparison; use the receiving institution’s conversion method for official reporting.
