km/h 

Often misspelt as kilometer.

The kilometre per hour is a unit of speed, expressing the number of kilometres travelled in one hour. The unit symbol is km/h. Worldwide, it is the most commonly used unit of speed on road signs and car speedometers.

Generally, speed limits, on most highway speed signs, are set to 100 km/h to 110 km/h.

F1 cars can accelerate to 300 km/h very quickly, due to their ability to gain RPM quickly. The top speeds, however, aren't much higher than 330 km/h on most circuits.
