French

Domaine(s)
  • Unités de mesure et métrologie
DEF

Unité de pression (1 333 baryes).

CONT

La pression atmosphérique est mesurée en pascals(unité du système international). Nous avons coutume, par simplicité de lecture, à utiliser un multiple de cette unité : l'hectopascal(hPa). La pression standard est PO=101325 Pa soit 1013, 25 hPa. Le pascal correspond au millibar autrefois employé. Il existe, en outre d’autres unités de mesure de la pression : le millimètre de mercure(mm Hg), l'atmosphère(atm), le pouce de mercure(in Hg).

CONT

[...] le millimètre de mercure : 776 mm de Hg = 1,013.105 Pa.

Spanish

Campo(s) temático(s)

DEF

Unidad de presión [casi] igual a 1 torriceli.

OBS

Un símbolo […] es una representación gráfica generalmente del ámbito científico con validez internacional: unidades básicas y derivadas del sistema internacional (kg, m, s), elementos químicos (S, de azufre; K, de potasio, o N, de nitrógeno), operaciones matemáticas (+, %), unidades monetarias ($, €), etcétera. Como se ve, a diferencia de las abreviaturas, que son siempre acortamientos gráficos de la palabra que desarrollan (tel., de teléfono), los símbolos son invariables en plural y no llevan punto abreviativo.
