Question

What are the units of measurement for atmospheric pressure? Which do you think is easiest to use? Explain why.

Answer 1

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

Answer 2

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?

Answer 3

atmospheres atm, kilopascals kpa, and millimeters of mercury mmHg. 1atm=101.3kpa=760mmHg you decide which is easiest to use based on your problem

Answer 4

1 Atmosphere=760 Torr

1 Torr=1mmHg
