Gigapascals to megapascals converter
Convert gigapascals (GPa) to megapascals (MPa). Calculate any value, follow the unit-factor steps and check a conversion table.
Updated · How we checkUse a decimal point, such as 2.5. Enter a value in GPa; the result is in MPa.
Formula
Worked example
Convert 1 GPa to MPa:
1 GPa ≈ 1,000 MPa
Multiply your GPa value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

What gigapascals measure
Gigapascals (GPa) represent pressure. One unit equals 10^9 Pa. One pascal is one newton per square meter. Pressure and mechanical stress share this unit.
Reading the result in megapascals
Megapascals (MPa) represent pressure. One unit equals 10^6 Pa. One pascal is one newton per square meter. Pressure and mechanical stress share this unit.
Where this conversion helps
Express a pressure measurement in the scale requested by an instrument or calculation. Converting units preserves the original gauge or absolute reference; it does not add or subtract atmospheric pressure.
How the scale changes
The input unit has a factor of 1e9 Pa; the output unit has a factor of 1e6 Pa. Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.
Reading very small or large results
Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
