As an Aussie I’ve used metric for everything my whole life, but I’ve just realised that everything I’ve ever used to inflate stuff has been metered in PSI. I just know that ~30PSI is good for tyres, ~15PSI is good for soccer balls.
I wouldn’t know the conversions because there’s no use for it because that’s not what the pumps use. Weird.
