Conversion Formula
nPa = mPa × 1000000
About Millipascals
A millipascal (mPa) is 10⁻³ Pa. It appears primarily in rheology as the millipascal-second (mPa·s = centipoise) for dynamic viscosity: water at 20°C is 1.002 mPa·s; olive oil ~80 mPa·s; honey 2,000-10,000 mPa·s. Food technology, polymer processing, pharmaceutical formulation, and inkjet printing all specify flow behaviour in mPa·s. Partial pressures of trace atmospheric gases and ultra-high-vacuum leak rates measured by residual gas analysers are also expressed in millipascals. 1 mPa = 10⁻³ Pa.
About Nanopascals
A nanopascal (nPa) is 10⁻⁹ Pa - the pressure scale of deep interplanetary space. LIGO and Virgo gravitational wave detectors must isolate mirror displacement signals against noise floors in the nanopascal regime. Low Earth orbit residual atmosphere is ~100 µPa; deep interplanetary space is ~1-10 nPa depending on solar wind activity. Thermospheric gas layers above 200 km altitude fall into the nPa-µPa range. Casimir force calculations and quantum vacuum fluctuation modelling also operate at nanopascal scales. 1 nPa = 10⁻⁹ Pa.
