Frequently asked questions
What is the source unit in this conversion?
The source unit is the Gigapascal (GPa). Gigapascal is 1000000000 pascal units.
What is the destination unit in this conversion?
The destination unit is the KSI (ksi). Kips per square inch.
How do I convert Gigapascal to KSI?
Multiply the Gigapascal value by 145.038. For example, 10 GPa × 145.038 = 1450.38 ksi.
Is the Gigapascal to KSI 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 Gigapascal needs to be compared with, or reported in, KSI, such as in engineering, scientific, or industrial calculations.
Can I convert KSI back to Gigapascal?
Yes. Multiply the KSI value by 0.00689476 to get Gigapascal.

About this conversion
This page converts Gigapascal (GPa) to KSI (ksi) within the engineering converter.
Gigapascal is 1000000000 pascal units. Kips per square inch.
The formula is ksi = GPa × 145.038, 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.
