Reverse: cmH2O = cmHg × 13.5951

Step-by-Step Example

Start with your value in cmH2O (4°C). For example: 5 cmH2O
Multiply by the conversion factor: 5 x 0.0735559135
The result is: 0.36778 cmHg

About cmH2O (4°C)

The cmh2o (4°c) (cmH2O) is a unit of pressure and stress. One cmh2o (4°c) equals 98.0665 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 cmHg (0°C)

The cmhg (0°c) (cmHg) is a unit of pressure and stress. One cmhg (0°c) equals 1333.223874 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.
