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 ) . In everyday life , the pascal is perhaps best known from meteorological barometric pressure reports , where it occurs in the form of hectopascals ( 1 hPa â 100 Pa ) or kilopascals ( 1 kPa â 1000 Pa ) .
