1 hectometer equals 109.3613298 yards (rounded).

1 hectometer = 109.3613298 yards

How to convert hectometers to yards

To convert hectometers to yards, multiply the number of hectometers by 109.3613298. The factor is rounded to 10 significant digits. To go the other way, multiply yards by 0.009144.

yards = hectometers × 109.3613298

Example: 10 hectometers = 1,093.613298 yards.

About these units

Hectometer (hm)

Metric (SI)Current unit

100 meters. An official SI unit, rarely used.

Hecto, the prefix for one hundred, dates to 1795 in Wikipedia's table of metric prefixes, which makes the hectometer (hm) a contemporary of the original French system. It equals 100 meters, one tenth of a kilometer, or about 328 feet. English speakers rarely use it, and the Wikipedia article flags even that claim as lacking a citation.

Its best-known appearance is hidden in another word. The hectare is a square hectometer, 10,000 square meters, so every land listing in hectares quietly rests on this length. A football pitch is about one hectometer long, and the Great Pyramid of Giza, at 137.7 m, stands about 1.377 hm high. Military writers have occasionally given target ranges in hectometers, with Wikipedia citing a 1927 Field Artillery Journal among its examples. The unit sits between the decameter at 10 m and the kilometer at 1,000 m.

1 hectometer = 100 meters (exactly).

Yard (yd)

US & ImperialCurrent unit

3 feet or 36 inches, exactly 0.9144 meters. Used for sports fields, fabric and short distances in the US and UK.

Yard descends from the Old English gerd or gyrd, meaning a branch, stave or measuring rod. It first appears in the late seventh-century laws of Ine of Wessex, though there it names a tax unit, the yardland. Around 959 to 963 King Edgar ordered that the measure held at Winchester be used throughout his realm, the earliest record of a prototype. A story that Henry I fixed the yard as the distance from his nose to his thumb is later folklore, and the true origin, whether pace, cubit or waist, remains speculative.

Britain defined the Imperial Standard Yard in 1824 as the distance between two marks on a brass rod at 62 degrees Fahrenheit. A fire in 1834 damaged the standard, a replacement was made in 1845, and the Weights and Measures Act 1855 recognized it. The 1959 international agreement then fixed the yard at exactly 0.9144 meter. Today it measures American and Canadian football fields, association football pitches and cricket pitches, appears on UK road signs for short distances, and is still used to sell fabric in the US and UK.

1 yard = 0.9144 meters (exactly).
