A Pascal (Pa) is the International Standard (SI) of derived units of the pressure or stress: 1 Pa = 1 N/m^2 = 1 kG/(m * s^2) = 1 J/m^3. The unit of measurement called standard atmosphere (atm) is defined as 101,325 Pa. Kilopascal (kPa) equals to 1000 Pa, and Hectopascal (1 hPa = 100 Pa) is equal to one millibar.
