Gas Pressure is measured in a variety of units.
Standard Temperature and pressure call for one atmosphere (1 atm) at
According to the wok of Evangelista Torrcelli, at sea level, 1 atm of air pressure will sustain a column of mercury at 760 mm meaning
1 atm = 760 mmHg or 1 atm = 760 torr (torrcellis)
In physics, the measure is completed in units called Pascals where 1 atm of gas is equivalent to 101,325 Pa or 101.3 kPa (kiloPascals).
In the United States where the System International (SI) is still just a fad, we can still find pressure in pounds per square inch or psi.
I hope this was helpful.
