About these units

Palm (palm)

Medieval EnglishHistorical unit (no longer in standard use)

3 inches (7.62 cm), about the breadth of a hand without the thumb. One of the oldest body-based units, used in many cultures with values of roughly 7 to 9 cm.

Open a hand flat and the part below the fingers gives the palm its name, which came through Old French from Latin palma, a word tied to a root meaning flat. As a measure it was the width of four fingers. Egyptian cubit-rods mark palms of about 7.5 cm from the reign of Djer in the First Dynasty, and Greek, Roman and Israelite palms fell between about 6.7 and 8.8 cm. In those systems three palms made a span and six a cubit.

In England the palm is given as 3 inches, or 7.62 cm, the figure used here, but the evidence is tangled, since the four-inch hand was sometimes confused with it and Wiktionary even glosses the English palm as four inches. Medieval Italy, France and Iberia used a much longer palm descended from the Roman greater palm, around 24.6 to 24.8 cm, while Morocco's was about 18.2 cm. The palm was left out of Britain's Weights and Measures Act of 1824 and is not a US customary unit.

1 palm = 0.0762 meters (exactly).

Mile (mi)

US & ImperialCurrent unit

5,280 feet or 1,760 yards, exactly 1,609.344 meters. This is the statute (international) mile used on US and UK roads.

A thousand paces gave the mile its name. It descends from the Latin mille passus, the Roman mile, by way of Old English mil and Middle English myle. For centuries after Rome, miles of many lengths coexisted; a sixteenth-century Mercator map, for example, shows small, medium and large Flemish miles on a single scale bar. The English statute mile was fixed by an Act of Parliament under Elizabeth I in 1593, which declared that a mile contains eight furlongs, or 5,280 feet.

The 1959 international yard and pound agreement made that mile exactly 1,609.344 meters. A slightly longer US survey mile, about 1,609.347 meters, lingered in American land surveys and was slated for retirement from 1 January 2023. Today the mile is the road unit of the United Kingdom, the United States, Liberia and Myanmar, along with several territories such as the Bahamas, Belize, Guam and the US Virgin Islands. In Canada it survives chiefly in rail transport and horse racing.
