About Megapascal
The megapascal (MPa) is a unit of pressure and stress. One megapascal equals 1.000000 × 10^+6 pascals. UnitConvertLab converts it against every other pressure unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
Common uses: pressure calculations, engineering and science, education.
About Atmosphere (std)
One standard atmosphere equals 101,325 Pascals and represents the average air pressure at sea level.
Common uses: diving, weather, chemistry.
