Force, in newtons, divided by area, in square meters, is pressure {pressure measurement} in pascals. Atmospheric pressure has pressure units {bar, pressure unit} {atmosphere, pressure unit} (atm). Pressure is how high mercury rises in columns {torr} {mm Hg} {inches Hg}. 1 atm equals 760 mm Hg. Standard temperature and pressure (STP) is 25 C and 1 atm. In English measure, pressure is force, in pounds, divided by area, in square inches {pounds per square inch} (psi).
