For the people who live in Canada this will make total sense.

Canada uses Metric but I must admit that majority of the time I use the imperial measurements.

E.g.

When driving I use Metric (km) speed (km)
For Temperature I use Celsius
Buying hardware for home I use Feet, inches
Height, use imperial again feet.
Weight once again imperial, lbs

I can go on and on. I can't speak for all Canadians but Majority will do what I do. At least in Toronto they do. Even when crime stoppers are describing a theft or murder they use imperial system to describe the dude.
