1 psi equals exactly
6,894.757 Pa
Psi (pounds per square inch) is defined in terms of the pound-force and the square inch, while the Pascal (Pa) is the base pressure unit of the International System, defined as one Newton per square meter. One psi is exactly equal to 6,894.757 Pa.
To convert a measurement from psi to Pascal, simply multiply the value by 6,894.757:
To convert from Pascal to psi, perform the inverse operation, dividing by 6,894.757:
This conversion is fundamental for scientists and engineers who need to express American psi-based measurements using the official SI unit, required for academic publications, international standards, and precise physics calculations.
