Let's say you're driving a car in the United States, and the speed limit is 55 miles per hour (mph). However, you're planning to travel to Canada, where the speed limit is given in kilometers per hour (kph).
You want to know how fast you can drive in kph without breaking the law.
To convert from mph to kph, you can use the formula:
Speed in kph = Speed in mph x 1.60934
Entering your numbers, you get:
Speed in kph = 55 mph x 1.60934 = 88.5137 kph
Therefore, the speed limit of 55 mph in the United States is equivalent to 88.5 kph in Canada.
This means that you should not drive faster than 88.5 kph when you reach Canada, in order to stay within the legal speed limit.
