You're probably like me being Canadian. I relate better to some measurements in metric and others in imperial and some I can go either way on because it's easy to convert in my head. PSI and Kpa is not super easy to do in your head and I can relate to psi better than I can kpa.
Perhaps the simplest thing to do in that case is just to remember two numbers: The first number to remember is the pressure you want the tires to be at so if that's 50 psi, remember 345.
The only other number you have to remember is the lowest pressure you will accept your tires being at. So if that's 30 psi, remember 207 or 210 to round it up.
That way you'll know that if you get a reading down near 210, you'd better act and get some air in there. If it's over 345 you should probably let a little air out of the tire. In between, you're good so don't worry.

What I don't get is why the Brits have Kilometers for distances but Miles per hour for speed.
But the answer still is Read your Owner Manual it tells you how to change the units. The difference is the made for Canada vehicles can go about a third faster than US models, our speedo only goes up to 120.

It goes back to the 1970's , our then PM thought it was a good idea, but the US never thought that! and neither did England . The world was to have agreed to be metric by the end of the decade and Canada fell for it!
