micropascal to pound-force per square inch
Convert micropascal (μPa) to pound-force per square inch (psi). Use an editable pressure converter, conversion formula, and reference table.
1 μPa = 1.45037738e-10 psi
Conversion formula
One micropascal equals 1.45037738e-10 pound-force per square inch. Multiply your value in micropascal by this factor to get pound-force per square inch. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 micropascal:5 × 1.45037738e-10 = 7.25188689e-10 psi

About these measurements
Pressure is force per unit of area.
The base reference used here is the pascal. One micropascal is 0.000001 base units; one pound-force per square inch is 6,894.757293 base units.
Important distinctions
Gauge and absolute pressures must not be mixed. This converts units without changing the reference pressure.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert μPa to psi?
