Atmospheric
pressure, sometimes also called barometric pressure, is the pressure exerted by the weight of air in
the atmosphere of Earth (or that of another planet)
1 atm is equivalent to = 101325
Pa
= 760 mmHg
= 760 torr
= 1.01325 bar
So 1.23 atm is equal to
= 124629.8 Pa
= 934.8 mmHg
= 934.8 torr
= 1.2462 bar
