Units explained
Kiloyard
A kiloyard is an Imperial unit of length equal to 1,000 yards (914.4 m). It is rarely used in everyday measurement but appears in some technical and military contexts.
The kiloyard combines the metric-style prefix kilo- (Greek chilioi, thousand) with the yard. Standardised via the 1959 International Yard and Pound Agreement.
Kiloyards appear in some artillery and military range specifications, sport-shooting long-range competitions, and certain industrial applications. Less common than the mile for most distances.
Modern usage; standardised through the 1959 International Yard and Pound Agreement.
Kilometer
A kilometer is a metric unit of length equal to one thousand meters. It is the standard unit for measuring road distances, geographic distances, and other large-scale measurements in metric countries.
The kilometer was defined alongside the meter in 1795 using the standard SI prefix kilo- (from Greek chilioi, "thousand"), denoting one thousand units.
Kilometers are used worldwide (except the United States and a few others) for road signage, geographic distance, athletic events, and scientific distances at planetary scale. Speed limits in most countries are given in km/h.
Adopted 1795 in France as part of the original metric system; the kilometer became the global standard for road and geographic distance through the 19th and 20th century metric adoption.
