### Different Pressure Definition

Could you say J/L instead of bar?

The SI unit is atm, but bar unit is more accurate. You could use J/L to find energy.

Just to add on, I think it really depends on what the question asks. Sometimes the question will ask you to convert the pressure to a certain unit, and that's when there is a requirement for the unit used.
