## Do we ever need to convert pressure?

Volume: $\Delta S = nR\ln \frac{V_{2}}{V_{1}}$
Temperature: $\Delta S = nC\ln \frac{T_{2}}{T_{1}}$

### Do we ever need to convert pressure?

Is there a standard unit of pressure for the equation $\Delta S = nRln\frac{P1}{P2}$

Like say they give it in atm, kPA, bar, etc. does it matter if I just use those units straight up or do I have to convert it to a standard unit like atm? From the textbook it doesn't seem like I have to, but I'm really not sure. Thanks!

In the equation that you mentioned, the pressure can be used in any units because they will cancel out as they are being divided.
