In scientific and technical writing, SI use requires that both the number and the unit name be expressed in full (e.g., fifteen kilometers) or that the numeral be followed by the symbol (e.g., 15 km). To aid comprehension, normal use permits digits with spelled-out unit names (e.g., 15 kilometers). Although these are acceptable forms of expression, brevity may require use of the abbreviated form.
Kilometer, km, K (kilometer), kilometres per hour, km2 SI use dictates that both the number and the unit name be expressed in full (e.g., fifteen kilometers) or that the numeral be followed by the symbol (e.g., 15 km). Non-SI countries often omit the unit name when writing out distances in miles or yards.
In English, French, and many other languages, there is no difference in spelling between a measure of distance and its associated unit of measurement. Thus, five kilometers (5 km) and 500 meters (500 m) are exactly equivalent ways of writing out the distance. The choice of which term to use depends on which part of speech the noun is in when it is used as a measure of distance.
Within the United States, the customary unit of measurement for roads is the mile. One kilometer is 0.624 mile. Therefore, six miles is equal to 16 kilometers. A mile is 5,280 feet, so 12 miles is 20,160 feet. A kilometer is 1000 meters, so 6 miles is 120,000 meters, or about 1.9 times as far as a mile.
The customary unit of measurement for railroads is the foot. One meter is 39 inches, so one kilometer is 0.62 mile. Therefore, six miles is 19.2 kilometers.
The kilometer (SI symbol: km; /'[email protected]: [email protected]/or/kI'[email protected]/), also spelled kilometer in American English, is a metric length unit equal to 1000 meters (kilo-being the SI prefix for 1000). The kilo is used with other units to form multiples of 1000, such as kilobyte and megabyte.
There are 1000 meters in a kilometer. Therefore, a kilometer is exactly 0.000999.. Miles (193.44 feet) or 1.1(0.0110) kilometers.
In terms of its part per thousand ratio to the meter, the kilometer is 0.0000001 (1e-7). In terms of its part per million ratio to the tonne, the kilometer is 4.35e-9 (441 ppm).
A kilometer is about 0.000621 mile or 914.44 yards. 1 kilometer is about 0.0833 mile or 125.72 yards. 1000 meters makes up a kibit (about 0.093 mile or 1453.04 yards), and 100 kibits make up a mi (about 0.5 mile or 763.8 yards).
At one kilometer per hour, it would take just over an hour to walk home from school.
A kilometer is represented by the symbol km, and its international spelling is kilometer. The meter is the basic unit for a kilometer, and the prefix is kilometer. One thousand meters equal one kilometer.
In the International System of Units, a kilometer (symbol: km) is a unit of length (SI). A kilometer is equal to 0.6214 mile. One kilometer equals one thousand meters. Modern usage of the term appears in many languages, such as English, Greek, Russian, and Vietnamese.
The identical sign, however, is used to represent "kilometers," which is plural. Recognize that 'km' is not a word.
The abbreviations k or K (pronounced /keI/) are often used to indicate kilometer, however they are not recommended by the BIPM.

Greek prefixes are used for units bigger than a meter: A kilometer is 1,000 meters; a kilometer is 1,000 meters. Prefixes are not needed for smaller units.
