Canada uses different measuring systems than the United States and for visitors who are unaware, it can potentially be problematic. For example, if you're driving in Canada, the speed limit is designated in kilometers per hour rather than miles per hour. Likewise, the temperature is measured in Celsius instead of Fahrenheit. These are little differences, but ones that could have an impact on your visit. The best way to calculate the temperature from Celsius to Fahrenheit is to use this simple equation: Degrees Celsius x 1.8 + 32 = Degrees Fahrenheit. You don't want to get stuck in a cold arctic snap in your swimsuit simply because of a miscalculation!
