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 0.000145. For example, 10 Pa × 0.000145 = 0.00145 psi.
Is the pascal to psi conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions 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 specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert psi back to pascal?
Yes. Multiply the psi value by 6894.757293 to get pascal.

About this conversion
This page converts pascal (Pa) to psi (psi) within the pressure converter.
The pascal is one newton per square meter. Pounds per square inch.
The formula is psi = pascal × 0.000145, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
