Frequently asked questions
What is the source unit in this conversion?
The source unit is the millipascal (mPa). Millipascal is 0.001000000000000000020816681712 pascal units.
What is the destination unit in this conversion?
The destination unit is the psi (psi). Pounds per square inch.
How do I convert millipascal to psi?
Multiply the millipascal value by 1.450377e-07. For example, 10 mPa × 1.450377e-07 = 0.000001 psi.
Is the millipascal 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 millipascal 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 millipascal?
Yes. Multiply the psi value by 6.894757e+06 to get millipascal.

About this conversion
This page converts millipascal (mPa) to psi (psi) within the pressure converter.
Millipascal is 0.001000000000000000020816681712 pascal units. Pounds per square inch.
The formula is psi = millipascal × 1.450377e-07, 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.
Use the calculator above for instant results, or the table below for common millipascal values already converted to psi.
