Frequently asked questions
What is the source unit in this conversion?
The source unit is the bar (bar). A bar is exactly 100,000 pascals.
What is the destination unit in this conversion?
The destination unit is the gigapascal (GPa). Gigapascal is 1000000000 pascal units.
How do I convert bar to gigapascal?
Multiply the bar value by 0.0001. For example, 10 bar × 0.0001 = 0.001 GPa.
Is the bar 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 bar 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 bar?
Yes. Multiply the gigapascal value by 10000 to get bar.

About this conversion
This page converts bar (bar) to gigapascal (GPa) within the pressure converter.
A bar is exactly 100,000 pascals. Gigapascal is 1000000000 pascal units.
The formula is gigapascal = bar × 0.0001, 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.
Use the calculator above for instant results, or the table below for common bar values already converted to gigapascal.
