Each year, millions of Americans cross the border into Canada to experience another country. Most of them drive. However, driving in Canada presents some challenges. Gas stations post their prices in liters. Speed limits are in kilometers. Americans often have trouble driving in this strange new world.

If you want to make it through Canada without running out of gas or getting a speeding ticket, you’ll need to be able to estimate conversions. If a gas station lists the price of gas at \$1.36, is that an incredibly good deal? Not really. There are almost 4 liters in a gallon. Do the math, and make sure you have enough money to fill your tank. Should you hit the gas or the brakes when the speed limit sign reads 100? You probably need to hit the brakes. Canadian highway speed limits are lower than most U.S. limits. If you exceed 55 miles per hour, you’ll run the risk of a ticket.

So why do people go to Canada if gas is more expensive and speed limits are lower? Because Canada is a land rich in history and culture. Heavily influenced by its French colonial past, the city of Montreal boasts unique architecture and cultural traditions. Toronto, whose skyline is shown above, is a true city of immigrants. The diverse mix of world cultures has produced exciting food and music scenes. With numerous national parks, Canada is also famous for its breathtaking natural beauty—and it’s only a drive away.
