micropascal to millipascal
Convert micropascal (μPa) to millipascal (mPa). Use an editable pressure converter, conversion formula, and reference table.
1 μPa = 0.001 mPa
Conversion formula
One micropascal equals 0.001 millipascal. Multiply your value in micropascal by this factor to get millipascal. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 micropascal:5 × 0.001 = 0.005 mPa

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 millipascal is 0.001 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 mPa?
Multiply the quantity in μPa by 0.001. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the millipascal to micropascal converter.
