Zebra, CFL uses yards.


I do agree that it could be because of machinery not wanting to be changed, and financial reasons.

However, we in Canada, while being Metric, use Imperial for some things. Such as cooking. Every single cooking instruction is in F. This is why we heat our ovens to 450 and not 230 (or whatever it would be in C, because I actually don't know).

Now, there is obviously good reason to not change to metric in the cases of machinery, however Canada is proof that just because you go Metric not everything changes with it. IE Ovens/Cooking.

The only things that would really change (worldwide) would be that countries with MPH would need to learn KPH, and Celsius opposed to Fahrenheit for outdoor temperature purposes.

As for learning Kilometer, I think it is rather easy - not because I know it, but because it's just plain easy.

1 KM = 1,000 Meters.
Everything is clean, and everything has an easy conversion.
It just seems to make a lot of sense for the age we live in to not be following a system that was enacted in the 1500's, and then minorly changed around in the 18th century.

It just boggles my mind.
