As much as I hate to admit it, a much younger version of me remembers life in Canada before the mid-1970’s.   Back when wearing helmets in the NHL wasn’t yet mandatory.   Seat belts weren’t mandatory.  The Metric System wasn’t in use yet.  Temperatures were in Fahrenheit, distance was in miles and speed was in miles per hour.  We measured in inches, feet and yards.  We officially switched to the Metric System on April 1, 1975 (not an April Fools joke) although as we know and experience every day, we are really a country of mixed measures as we utilize both Systems.  I admit if you ask me how tall I am I will say 5 feet 10 inches.  Yes, I know that’s 1.78 metres but, seriously, isn’t “5-10” so much quicker and easier to say?   We are OK now with kilometres (or as most people say, kill-AH-metres).  Kilometres is correct or we should say cen-TIM-metres and mil-LIM-metres instead of centimetres and millimetres.   We are also used to Celsius temperatures although I sometimes do find myself thinking that plus 20 is 68 F, 25 is 77 (and a perfect summer day), and above 32 it’s getting into the 90’s and hot.  How about sports?  Can you imagine in football hearing “It’s 3rd down with just 0.9 metres (or 90 centimetres) to go instead of a yard?  I guess we could get used to it but, brother!   Why is Canada not 100% Metric?  The influence of the United States of America.  So, is it time to go all Metric in everything everywhere?  Some people think so.
