Frequently asked questions
What is the source unit in this conversion?
The source unit is the Pascal (Pa). The pascal is one newton per square meter.
What is the destination unit in this conversion?
The destination unit is the PSI (psi). Pounds per square inch.
How do I convert Pascal to PSI?
Multiply the Pascal value by 0.000145038. For example, 10 Pa × 0.000145038 = 0.00145038 psi.
Is the Pascal to PSI conversion exact?
Yes. Both units belong to the same engineering measurement family (pressure and mechanical stress), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in Pascal needs to be compared with, or reported in, PSI, such as in engineering, scientific, or industrial calculations.
Can I convert PSI back to Pascal?
Yes. Multiply the PSI value by 6894.76 to get Pascal.

About this conversion
This page converts Pascal (Pa) to PSI (psi) within the engineering converter.
The pascal is one newton per square meter. Pounds per square inch.
The formula is psi = Pa × 0.000145038, based on each unit's fixed relationship to the pressure and mechanical stress base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
