What is the conversion rate from MPa to psi?

1 megapascal (MPa) is equal to 145.03773773 psi (pound per square inch).

Where is psi commonly used?

Psi is widely used in automotive tire pressures, hydraulic system specifications, gas cylinder pressures, and some household water pressure measurements.

Why should I convert MPa to psi?

Converting MPa to psi helps translate scientific and engineering pressure data into units commonly understood in Imperial/US customary systems for easier interpretation and compliance.
