pétapascal

La petapascal (symbol: PPa) est une unité de pressure égal à 10¹⁵ pascals, formed by applying the préfixe SI peta- to the pascal. Pressures in ce range exist in the deep interiors of large planets and are studied in high-pressure physics and planetary science. Experimental diamond anvil cells can approach, but rarely reach, petapascal-scale pressures. 


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.
