GPA to Percentage Calculator
There is no single official GPA-to-percentage formula in the US, but a common approximation is Percentage = GPA × 25. So 3.5 GPA equals 87.5%. This calculator also supports the more accurate letter-grade-based mapping (A = 95%, A- = 92%, B+ = 88%, etc.).

Frequently Asked Questions
Why does GPA-to-percentage have no single formula?
The US grading system is letter-based at its source. Percentages are derived locally per school or course. There is no national standard mapping, so any conversion is an approximation.
Which formula should I use for grad school applications?
If the school accepts a stated GPA, use that. If they require a percentage, use the linear GPA × 25 method but include a note that the conversion is approximate.
Why does an A- only translate to 92% and not 90%?
Most US schools define A- as 90-92.9%, so 92 is the midpoint. Schools that use a different boundary (e.g., A- = 90-93) shift the midpoint accordingly.
Can I use this for high school GPA?
Yes — the same conversion applies. A 3.5 unweighted high school GPA is roughly 87.5%. Weighted GPA above 4.0 should use the unweighted equivalent first.
