Convert gigapascal to megapascal
Please provide values below to convert gigapascal [GPa] to megapascal [MPa], or Convert megapascal to gigapascal.
How to Convert Gigapascal to Megapascal
1 GPa = 1000 MPa
Example: convert 15 GPa to MPa:
15 GPa = 15 × 1000 MPa = 15000 MPa

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.
Megapascal
The megapascal (MPa) is a unit of pressure equal to one million pascals, where one pascal (Pa) is the pressure exerted by a force of one newton per square meter.
History/Origin
The megapascal was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring high pressures, especially in engineering and scientific applications, replacing larger units like the bar in many contexts.
Current Use
The MPa is widely used today in engineering, material science, and industrial applications to specify pressures in fields such as hydraulics, pneumatics, and structural engineering.
