Pascal (Pa)
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 metre. In everyday life, the pascal is most commonly used in the form of kilopascal (1 kPa = 1000 Pa). One kilopascal corresponds to about 1% of atmospheric pressure (near sea level).
