I guess as long as it works it works. I don’t have to do much of those conversions though. Here in Norway we are metric in almost all of our measurements. Except for some specialist measures like a carton of eggs is a dozen. We often say things happened a fortnight or so ago, etc.
just multiplying or dividing by 1.6 is about as accurate as my strategy in the other direction - the real value is almost exactly between them.
