Convert bar to gigapascal
Please provide values below to convert bar [bar] to gigapascal [GPa], or Convert gigapascal to bar.
1 bar = 0.0001 GPa. To convert bar to gigapascal, multiply the value by 0.0001; to go the other way, divide by it (1 GPa = 10000 bar). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 bar = 0.0001 GPa
- 1 GPa = 10000 bar
- 10 bar = 0.001 GPa
- 100 bar = 0.01 GPa
How to Convert Bar to Gigapascal
1 bar = 0.0001 GPa
Example: convert 15 bar to GPa:
15 bar = 15 × 0.0001 GPa = 0.0015 GPa

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.
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.
Frequently Asked Questions
What is 1 bar in gigapascal?
1 bar (bar) = 0.0001 gigapascal (GPa).
How do you convert bar to gigapascal?
Multiply the bar value by 0.0001. For example, 25 bar × 0.0001 = 0.0025 GPa.
What is 10 bar in gigapascal?
10 bar = 0.001 GPa.
Which unit is larger, the bar or the gigapascal?
The gigapascal is the larger unit: 1 bar equals only 0.0001 GPa.
