Turn a US 4.0 GPA back into a percentage —by the linear rule, by the letter band it implies, and by your university's formula. The reverse direction is not an exact inverse; this page shows you the range instead of pretending otherwise.
A few institutions use ×24 or ×25.5-style adjustments; if yours publishes a factor, use it. Otherwise stick with ×25.
3.4 clears the common 3.0 floor —good standing for most US master's programmes.
The percentage version of a GPA matters less than the GPA itself on a US application. Keep the transcript and grading key as your primary document; convert only when a form demands a percentage.
The forward conversion maps wide percentage bands onto single GPA points. A 3.5 can be an 85, an 87, or anything else inside its band —so going backwards, the honest answer is a range. Anyone who gives you one precise percentage for a 3.4 is picking a convention, not reporting a fact.
3.4 →85%. Clean, reproducible, and what most forms assume. It is a convention, not a conversion —it ignores that US grades are letters first.
3.4 is a B+, and B+ on a typical US 100-point scale is the 85–9% band. This respects how grades actually work, at the cost of a single number.
Use linear when a form forces one number, and use the band range when you want an honest answer. Label whatever you send with its method —'85% (GPA 3.4 × 25)' —and keep the transcript as the primary document.
If you're also converting credits for the same application, the credit pair lives over at ECTS →US credits and US credits →ECTS.
Multiply the GPA by 25. 3.0 →75%, 3.4 →85%, 3.7 →92.5%. The standard assumption behind most percentage fields on application forms.
Read the GPA as a letter grade, then take the percentage range that grade occupies on a typical US scale. Output is a range because the input really is one.
If your institution publishes its own GPA→Percentage factor, use it. Their convention is the one that institution will recognise.
US admissions read the GPA and the grading key directly. A self-converted percentage is a convenience for forms, not a substitute document. If the programme accepts the GPA, report the GPA.

Letter bands are the typical US 100-point convention; individual institutions vary. The linear column shows why the two methods diverge as GPA rises.
