Canada uses the international metric system. The following conversions may be helpful:

1 Canadian gallon = 4.5 litres
1 American gallon = 3.8 litres
Miles x 1.6 = Kilometres
Kilometres x 0.6 = Miles
30°C = 86°F
20°C = 68°F
0°C = 32°F
-10°C = 14°F
30 mph = 50 kph

Electricity
Canada operates on 110V, 60 cycle electric power (same as the U.S.). Non-North American visitors should bring a plug adaptor if you wish to use your own small appliances from home (i.e. razors, hair dryers). If you are visiting from countries such Australia, that use a higher voltage, you may encounter problems charging your re-chargeable batteries. Canadian electrical goods come with either a two-pronged plug (same as the U.S.), or a three-pronged plug, most sockets accommodate both.

Weights & Measures
While Canada changed to the metric system in the 1970’s we still use both the Imperial and Metric system. All speed-limit signs are in metric (i.e. kilometres/hour) and gasoline is sold in litres. Fresh goods and meat are primarily sold by the pound, and a metric breakdown is normally provided.
