atmosphère technique

La technical atmosphere (at) est une unité non-SI de pressure défini comme the pressure exerted by one kilogram-force on a surface of one carré centimeter, égal à exactement 98,066.5 pascals. It differs from the standard atmosphere (atm), qui is slightly larger at 101,325 Pa. La technical atmosphere was widely utilisé en older European and Soviet engineering practice before unité SIs became standard. 


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.
