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.

About ftH2O (4°C)

The fth2o (4°c) (ftH2O) is a unit of pressure and stress. One fth2o (4°c) equals 2989.0669 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.
