Centimeter of mercury

La centimeter of mercury (cmHg) is a manounité métrique de pression égal à 10 millimeters of mercury, or approximativement 1,333.22 pascals. Il est défini comme the pressure exerted by a 1 cm column of mercury at 0 °C under standard gravity. While less common than mmHg, it appears in some older medical and scientific literature. 


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.
