Convert gigapascal to bar
Please provide values below to convert gigapascal [GPa] to bar [bar], or Convert bar to gigapascal.
1 GPa = 10000 bar. To convert gigapascal to bar, multiply the value by 10000; to go the other way, divide by it (1 bar = 0.0001 GPa). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 GPa = 10000 bar
- 1 bar = 0.0001 GPa
- 10 GPa = 100000 bar
- 100 GPa = 1000000 bar
How to Convert Gigapascal to Bar
1 GPa = 10000 bar
Example: convert 15 GPa to bar:
15 GPa = 15 × 10000 bar = 150000 bar

Gigapascal
A gigapascal (GPa) is a unit of pressure equal to one billion pascals, where one pascal (Pa) is the force of one newton per square meter.
History/Origin
The gigapascal was introduced as part of the International System of Units (SI) to measure high-pressure phenomena, especially in materials science and geophysics, as a larger unit than the pascal for convenience.
Current Use
GPa is commonly used to quantify stress, pressure in geological formations, material strength, and high-pressure physics applications.
Bar
The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.
History/Origin
The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.
Current Use
The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
Frequently Asked Questions
What is 1 gigapascal in bar?
1 gigapascal (GPa) = 10000 bar (bar).
How do you convert gigapascal to bar?
