Convert gigapascal to microbar
Please provide values below to convert gigapascal [GPa] to microbar [µbar], or Convert microbar to gigapascal.
How to Convert Gigapascal to Microbar
1 GPa = 10000000000 µbar
Example: convert 15 GPa to µbar:
15 GPa = 15 × 10000000000 µbar = 150000000000 µbar

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.
Microbar
A microbar (µbar) is a unit of pressure equal to one millionth of a bar, where 1 bar equals 100,000 pascals.
History/Origin
The microbar was introduced as a subunit of the bar to measure very low pressures, particularly in meteorology and vacuum technology, gaining usage in the 20th century as precision pressure measurements became more common.
Current Use
Today, the microbar is used primarily in meteorology for measuring atmospheric pressure variations and in scientific research requiring precise low-pressure measurements.
