Half of my schooling was with the imperial system and then the metric system was introduced. I understand and use both but need to convert some numbers. I prefer pounds for weight, gallons for liquids and inches/feet for construction. Long distance has me use kilometres and I prefer Celsius for temperature.
I work in the electrical distribution industry and we still measure our towers and poles in feet yet our conductor lengths are in meters. Kinda screwy if you think about it.
Canada didn’t go all in for the metric system because our largest trading partner didn’t join.
