Frequently asked questions
What is the source unit in this conversion?
The source unit is the psi (psi). Pounds per square inch.
What is the destination unit in this conversion?
The destination unit is the micropascal (uPa). Micropascal is 0.000000999999999999999954748112 pascal units.
How do I convert psi to micropascal?
Multiply the psi value by 6.894757e+09. For example, 10 psi × 6.894757e+09 = 6.894757e+10 uPa.
Is the psi to micropascal 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 psi needs to be compared with, or reported in, micropascal, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert micropascal back to psi?
Yes. Multiply the micropascal value by 1.450377e-10 to get psi.

About this conversion
This page converts psi (psi) to micropascal (uPa) within the pressure converter.
Pounds per square inch. Micropascal is 0.000000999999999999999954748112 pascal units.
The formula is micropascal = psi × 6.894757e+09, 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 psi values already converted to micropascal.
