About Megapascals
A megapascal (MPa) = 10⁶ Pa = 10 bar - standard unit for mechanical stress, material strength, and high-pressure engineering. Structural material yield strengths: mild steel 250-550 MPa; high-strength steel to 2,000 MPa; carbon fibre composites 1,500-7,000 MPa tensile. Hydraulic press pressures 50-200 MPa. Mariana Trench floor ~110 MPa. Concrete compressive strength: 25-40 MPa (normal); up to 150 MPa (high-performance). Water-jet cutting: 200-600 MPa. Elastic moduli in FEM analysis are in MPa or GPa. 1 MPa = 10⁶ Pa = 145.0 psi.
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.
