1 atm
torr
psi
pascal

atm is by far the easiest to use because it requires less conversion

1 atm = 760 torr

but the SI unit for atmospheric pressure is pascal so if u need that there u go

millibars, 29.92 @ sea level on a standard day( 69 degrees F). Look in any scientific book.  listen to your local weather forcast on the news or paper. they will give the presure in millibars. A rising pressure usually means nice weather is comming. a falling pressure usually means the opposite. Can't remember if it was 59 or 69 degrees for a standard day temp. Let me know if I was incorect. Ok?
