Haha! Yeah, we are weird over here! Still buy milk and gas by the gallon, temperatures are in Fahrenheit...would be nice if it was all universal, but of course we are slow to adopt a new system. Of course we were taught the formula for translating Fahrenheit to Celsius (or do you call it Centigrade???), but it's one of those things we don't really use. I will tell you, learning to change weight from pounds came in handy, because meds are based on how much the animal weighs in kilograms!
Oh yeah, what is an "arvo (avro? )"?? Is that akin to our "afternoon"? Lol
