Units explained
Hectometer
A hectometer is a metric unit of length equal to one hundred meters (100 m). It is occasionally used in sports, agricultural surveying, and some European real-estate contexts.
The hectometer was defined alongside the meter when France adopted the metric system in 1795, using the SI prefix hecto- (from Greek hekaton, hundred) to denote multiplication by 100.
Hectometers appear in some sports contexts (the 100 m sprint is technically 1 hm), in agriculture (parcel sizes in some European nations), and in atmospheric science. Most contexts now use meters or kilometers instead.
Adopted in 1795 in France; ratified through the Metre Convention of 1875; remains a defined SI prefix unit although rarely used outside specialised contexts.
Yard
A yard is an Imperial and US customary unit of length equal to 3 feet or exactly 0.9144 meters. It is used for medium distances, particularly in athletics and fabric/textile measurement.
The yard's origin is contested but traditionally attributed to the length from the tip of King Henry I's nose to the end of his outstretched thumb. It was standardized in English law from the medieval period and definitively fixed at 0.9144 m exactly by the 1959 International Yard and Pound Agreement.
Yards are used in American football (10 yards for a first down), golf course distances, fabric and carpet sales in the US, and short-distance running events. The UK uses yards informally and on road signs for short distances.
Standardized in English law from the Middle Ages; fixed at 0.9144 m exactly by the 1959 International Yard and Pound Agreement.
