About Atmosphere (std)
One standard atmosphere equals 101,325 Pascals and represents the average air pressure at sea level.
Common uses: diving, weather, chemistry.
About Kilopascal
The kilopascal (kPa) is a unit of pressure and stress. One kilopascal equals 1000 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.
