Pete 350Z Turbo

I couldn't find any answer to my question on the web nor in this forum, so I am hoping someone could help. The oil pressure sensor on my 2004 350Z is not working anymore and it needs to be replaced. The problem I have is that my car isn't a U.S. car, thus the readings of the gauge are in metric (SI) units and not PSI (mine goes from 0 to 8 bar and not from 0 to 120 PSI). So the question is: do I need to look for a sensor that supports metric units or can I buy any sensor in the market? I wanted to order one from the U.S. since my friend is coming to visit, but I was afraid it wouldn't work since the pressure measuring unit in the U.S. is in PSI. Thanks for your support!
