About Bar
The bar is a metric unit of pressure equal to 100,000 Pascals, roughly equal to atmospheric pressure at sea level.
Common uses: tire pressure, industrial, meteorology.
About mmH2O (4°C)
The mmh2o (4°c) (mmH2O) is a unit of pressure and stress. One mmh2o (4°c) equals 9.80665 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.
