Glossary » Units » Pressure » Millimeter of Water (4°C)
Millimeter of Water (4°C) (mmH2O, mmCE (4 °C)) is a unit in the category of Pressure. It is also known as millimeters of water, millimetre of water, millimetres of water, millimeters of H2O, millimetre of H2O, millimetres of H2O, millimeter of H2O. Millimeter of Water (4°C) (mmH2O, mmCE (4 °C)) has a dimension of ML-1T-2 where M is mass, L is length, and T is time. It can be converted to the corresponding standard SI unit Pa by multiplying its value by a factor of 9.806375414.
Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).
