Units for pressure

[Ashley Kenney 1E]

When calculating work, does it matter what unit of pressure is being used? Or should we convert whatever unit of pressure we are given to atmospheres?

[Ronald Thompson 1F]

For a final answer I believe you want to use atm unless otherwise stated. You might have to do some conversions (Torr to atm)

[Lasya Gudipudi 1A]

To play it safe, I would just convert to atmospheres anytime you are asked for pressure.

[SydBenedict2H]

If its ever in bar, thats more or less equivalent to atm.

[MichaelMoreno2G]

If its ever in bar, thats more or less equivalent to atm.

Exactly, I remember the professor saying the difference between bar and atm is very small.

[kateminden]

Yeah, I believe generally we would use atm unless a different unit was given in a specific problem.

[405021651]

Usually atm is used!

[Mercan Bayazit 4E]

Yes, I think we generally use atm for pressure, even though the difference is small.

You would normally use atm or bar as units in your answer.

[Nicolle Fernandez 1E]

You would preferably use atm but using bar is okay bc the difference between atm and bar is so small

Refer to the constants and go from there. If the problem gives you torr, and whatever constant you're using uses atm, then make sure to use atm in order to be able to cancel them out properly.
