Centimeter of Water (4°C)
Centimetre of water at 4°C (cmH₂O) is a unit of pressure defined as the pressure exerted by a one-centimetre column of water at its maximum density temperature of 4°C, equal to approximately 98.0638 pascals. It is used in medicine and biomedical engineering to express pressures such as central venous pressure and cerebrospinal fluid pressure. The unit reflects the historical use of water columns as simple pressure gauges.
Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square metre (N/m²). It was adopted by the General Conference on Weights and Measures in 1971 and named after the French mathematician and physicist Blaise Pascal. Standard atmospheric pressure is approximately 101,325 Pa, and it is widely used in science, engineering, and meteorology.
