In this regard I'm wondering if all provinces switched over at the same time. I have two distinct recollections, my first encounter with gas over $1 a gallon was at Chetwynd B.C. in July 1977 when it was $1.016 and the second was when it reached $0.25 per litre.
Chetwynd is seared into my memory, but for different reasons. Wow, I knew we had the highest gas prices in the GTA at the time and hit $1/gal a few years before that, but I can't remember what year, but prices did fall. I was delivering pizza in the mid 70's so I was cognizant of prices, (I used my own car and paid my own gas), and remember gas in the $.25/l range.
And getting back to basics the metre was adopted as at the time it was calculated to be 1/10 millionth of the dist. from the equator to the pole, but that was found later to be in error, so it was changed to a distance between two marks on a metal bar in Paris, but that wasn't good enough for long so now it's based on some formula involving such nonsense as the colour of light at a certain temp. (Can't remember the details of that one at all, and can't really see my future depending upon knowing it!) -![]()
And who says Imperial is more arbitrary than metric?
