Convert Standard atmosphere to gigapascal
Please provide values below to convert Standard atmosphere [atm] to gigapascal [GPa], or Convert gigapascal to Standard atmosphere.
How to Convert Standard Atmosphere to Gigapascal
1 atm = 0.000101325 GPa
Example: convert 15 atm to GPa:
15 atm = 15 × 0.000101325 GPa = 0.001519875 GPa

Standard Atmosphere
The standard atmosphere (atm) is a unit of pressure defined as 101,325 pascals, representing the average atmospheric pressure at sea level.
History/Origin
The standard atmosphere was established in the early 20th century to provide a consistent reference for pressure measurements, based on the average atmospheric pressure at sea level under standard conditions.
Current Use
The atm is commonly used in fields such as meteorology, aviation, and engineering to express pressure, especially in contexts involving gases and atmospheric conditions.
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.
