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 (tech)

The atmosphere (tech) (at) is a unit of pressure and stress. One atmosphere (tech) equals 98066.5 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.
