Kilometers per hour
Kilometers per hour is a unit of measurement using length in kilometers and time in hours, and thus it acts as a derived unit for both speed and velocity. The proper shorthand for this unit is km/h,[1] however kph or kmph are sometimes used.
Traffic speed limits in Canada are posted in km/h in addition to automobile speedometers for the country using the same units. Both speed and velocity are measured by taking the distance traveled during some duration, and dividing that length by a time.
Examples
- Road speed limitations in Canada range anywhere from 10 km/h (6.2 mph) to 120 km/h (74.6 mph)
- With a destination in mind, cycling speeds are around 15 km/h (as opposed to casual cycling, which can be much slower)
- Recreational swimming ranges somewhere between 1-5 km/h. World records are no faster than 9 km/h
