Centimeter of Water (4°C)

Centimetre of water at 4°C (cmH₂O) est une unité de pressure défini comme the pressure exerted by a one-centimetre column of water at its maximum density temperature of 4°C, égal à approximativement 98.0638 pascals. Il est utilisé en medicine and biomedical engineering to express pressures tel que central venous pressure and cerebrospinal fluid pressure. The unit reflects the historical use of water columns as simple pressure gauges. 


pascal

La pascal (Pa) is the unité SI dérivée de pression, défini comme one newton per carré metre (N/m²). Il était adopted by the General Conference on Weights and Measures in 1971 and nommé d'après the French mathematician and physicist Blaise Pascal. Standard atmospheric pressure is approximativement 101,325 Pa, and il est widely utilisé en science, engineering, and meteorology.
