Hectopascal (hPa)
The pascal (symbol: Pa) is the SI derived unit of pressure or stress (also: Young's modulus and tensile strength). It is equivalent to one newton per square meter. In everyday life, the pascal is most commonly used in the form of hectopascal (1 hPa = 100 Pa). One hectopascal corresponds to about 1‰ of atmospheric pressure (near sea level).
