Gigapascal to megapascal Conversion
1 gigapascal (GPa) is equal to 1000 megapascal (MPa).
1 GPa = 1000 MPa
or
1 MPa = 0.001 GPa
Formula
To convert a pressure from gigapascal (GPa) to megapascal (MPa), multiply the pressure in gigapascal by 1000
p(MPa) = p(GPa) × 1000
Examples:
Convert 2 gigapascal to megapascal:
p(MPa) = 2GPa × 1000 = 2000 MPa

Frequently asked questions
How do I convert gigapascal to megapascal?
Multiply the value in gigapascal by 1000 to get the result in megapascal. For example, 5 GPa × 1000 = 5000 MPa.
How many megapascal are in 1 gigapascal?
1 gigapascal (GPa) is equal to 1000 megapascal (MPa).
How do I convert megapascal back to gigapascal?
Use the inverse operation: divide the value in megapascal by 1000 to get the result in gigapascal.
How accurate is the gigapascal to megapascal conversion?
The converter multiplies by the conversion factor 1000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
