I was in Grade 8 when the metric system was introduced in Canada so I can work in Imperial and Metric.

It is odd but Canadians almost always use both systems.

Personal height and weight are usually referred to in Imperial, but temperature and distances are referred to in metric.

I still do contruction in Imperial because dimensional lumber is cut in the old standard sizes (e.g. 4' x 8' plywood).

There really are few fractions in the metric system. If something is smaller than a meter then you measure it in centimeters or millimeters if it is really small.

Water freezes at 0*c, boils at 100*c and a litre weighs one kilogram.

It is an odd system at first (like everything else that is new) but after a while it makes a lot of sense.
