Pascal (unit)
From the Simple English Wikipedia, the free encyclopedia that anyone can change
The pascal (symbol: Pa) is the SI derived unit of pressure or stress. It is a measure of vertical force per unit area i.e. equal to one newton per square meter. In everyday life, the pascal is maybe best known from meteorological air-pressure reports, where it happens in the form of hectopascal (1 hPa = 100 Pa).[1] In other cases, the kilopascal is more commonly used, for example on bicycle tire labels[2]. One hectopascal corresponds to about 0.1% and one kilopascal to about 1% of atmospheric pressure (near sea level).
