Our megapascal to psi converter provides precise pressure conversions between metric and imperial units for engineering, manufacturing, and industrial applications.
*MPa (megapascals) is metric, PSI (pounds per square inch) is imperial
Supports decimal values (e.g., 2.5, 0.35 MPa)
Precision: 2 Decimal Places | 1 MPa = 145.03773773 PSI
Understand how to convert between megapascals and pounds per square inch for engineering applications.
MPa is part of the metric system (SI units), while PSI is an imperial unit commonly used in the United States.
Use the formula: PSI = MPa × 145.03773773
Example: Convert 2.5 MPa to PSI
2.5 × 145.03773773 = 362.5943443 PSI
Use the formula: MPa = PSI × 0.00689476
Example: Convert 500 PSI to MPa
500 × 0.00689476 = 3.44738 MPa
Use these approximate conversion factors for quick estimates:
