Speed limit sign in the Republic of Ireland, using "km/h.". The SI representations, classified as symbols, are "km/h", "km h −1" and "km·h −1".Several other abbreviations of "kilometres per hour" have been used since the term was introduced and many are still in use today; for example, dictionaries list "kph", [3] [4] [5] "kmph" and "km/hr" [6] as English abbreviations.
The cheetah can accelerate from 0 to 96.6 km/h (60.0 mph) in under three seconds, [58] though endurance is limited: most cheetahs run for only 60 seconds at a time. [19] When sprinting, cheetahs spend more time in the air than on the ground. [59] See Sarah, the fastest cheetah.
The time it takes a vehicle to accelerate from 0 to 60 miles per hour (97 km/h or 27 m/s), often said as just "zero to sixty" or "nought to sixty", is a commonly used performance measure for automotive acceleration in the United States and the United Kingdom. In the rest of the world, 0 to 100 km/h (0 to 62.1 mph) is used.
A Suzuki GSX-R1000 at a drag strip – a 2006 model once recorded a 0 to 60 mph time of 2.35 seconds. This is a list of street legal production motorcycles ranked by acceleration from a standing start, limited to 0 to 60 mph times of under 3.5 seconds, and 1 ⁄ 4-mile times of under 12 seconds.
Prior to 2009, a speed limit could be defined in kilometers per hour (km/h) as well as miles per hour (mph). The 2003 version of the MUTCD stated that "speed limits shown shall be in multiples of 10 km/h or 5 mph." [ 118 ] If a speed limit sign indicated km/h, the number was circumscribed and "km/h" was written below.
Highest-posted speed limits around the world. Kilometres per hour are on the left and miles per hour on the right.* A speed limit is the limit of speed allowed by law for road vehicles, usually the maximum speed allowed.
Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the knot is commonly used.
The UK national speed limit of 60 miles per hour (97 km/h) for ordinary vehicles applies beyond this sign. In some countries, derestriction signs are used to mark where a speed zone ends. The speed limit beyond the sign is the prevailing limit for the general area; for example, the sign might be used to show the end of an urban area.
