Frequently asked questions
What is the source unit in this conversion?
The source unit is the PSI (psi). Pounds per square inch.
What is the destination unit in this conversion?
The destination unit is the Gigapascal (GPa). Gigapascal is 1000000000 pascal units.
How do I convert PSI to Gigapascal?
Multiply the PSI value by 6.89476e-06. For example, 10 psi × 6.89476e-06 = 6.89476e-05 GPa.
Is the PSI to Gigapascal conversion exact?
Yes. Both units belong to the same engineering measurement family (pressure and mechanical stress), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in PSI needs to be compared with, or reported in, Gigapascal, such as in engineering, scientific, or industrial calculations.
Can I convert Gigapascal back to PSI?
Yes. Multiply the Gigapascal value by 145038 to get PSI.

About this conversion
This page converts PSI (psi) to Gigapascal (GPa) within the engineering converter.
Pounds per square inch. Gigapascal is 1000000000 pascal units.
The formula is GPa = psi × 6.89476e-06, based on each unit's fixed relationship to the pressure and mechanical stress base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
