Conversion Formula
nPa = Pa × 1000000000
About Pascals
The pascal (Pa) is the SI unit of pressure - 1 N/m², named after Blaise Pascal (1623-1662). Standard sea-level atmosphere ≈ 101,325 Pa. One pascal is very small: roughly the pressure of a single banknote lying flat. Pascal is simultaneously the SI unit for mechanical stress and elastic modulus: structural steel Young's modulus ~200 GPa; rubber shear modulus ~0.5 MPa. Used universally in fluid mechanics, acoustics, atmospheric science, and materials engineering. 1 Pa = 1 N/m².
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.
