About these units
Ken (ken)
The ken is a traditional Japanese unit of length, typically about 1.8 meters, though historically it ranged from 1.6 to 1.9 meters depending on the era and region. The ken is deeply tied to traditional Japanese architecture, especially temple and shrine construction. In classic building design, the ken measured the spacing between pillars in wooden structures. Because Japanese architecture emphasizes modularity and harmonious proportions, the ken allowed builders to create spaces that were both structurally efficient and aesthetically consistent. Many tatami room layouts are also derived from ken-based proportions. Beyond architecture, the ken carried symbolic importance in religious and cultural contexts. Temples were often laid out using ken multiples, reinforcing a sense of order, symmetry, and sacred geometry. Even though modern Japan uses the metric system, the ken persists in the restoration and preservation of historical buildings.
Furlong (fur)
A furlong, equal to 10 chains or 660 feet, originated as the distance a team of oxen could plow before needing rest. Its name derives from "furrow-long," indicating the length of a typical plowed furrow in medieval agriculture. This agricultural basis linked the furlong to the acre: a rectangle one furlong long and one chain wide equaled one acre in area. Today, the furlong is most notably used in horse racing, where race distances are often measured in furlongs rather than miles. This tradition reflects both the unit's historical importance and its suitability for describing moderate distances. While archaic in most contexts, the furlong remains a culturally iconic measure that connects modern sports to medieval agricultural practices.
