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 0.000007. For example, 10 psi × 0.000007 = 0.000069 GPa.
Is the psi to gigapascal conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions 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 specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert gigapascal back to psi?
Yes. Multiply the gigapascal value by 145037.73773 to get psi.

About this conversion
This page converts psi (psi) to gigapascal (GPa) within the pressure converter.
Pounds per square inch. Gigapascal is 1000000000 pascal units.
The formula is gigapascal = psi × 0.000007, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
