About these units

Royal Cubit (cubit)

Ancient EgyptianHistorical unit (no longer in standard use)Approximate value

The standard Egyptian cubit of about 52.5 cm (20.7 in), divided into 7 palms of 4 fingers. Surviving cubit rods were used to lay out the pyramids.

Among the earliest standard measures on record is the royal cubit, written meh niswt, meaning the cubit of the king. The English word cubit comes from Latin cubitum, the elbow, since the unit was first the forearm. The Egyptian version ran longer than the common cubit, holding seven palms of four fingers, or 28 fingers, against 24 for the ordinary one. It appears in Old Kingdom building work from at least the Step Pyramid of Djoser, around 2700 BC.

Our knowledge of its size comes from physical rods. Richard Lepsius compared fourteen of them in 1865, and examples from the tombs of Maya at Saqqara and Kha at Thebes survive, one folding rod being in the Museo Egizio in Turin. Measured rods fall between about 523.5 and 529.2 mm, so the 52.5 cm used here is one common estimate within that range. In modern terms the cubit is roughly 20.6 to 20.8 inches, a little over half a metre.

1 royal cubit = 0.525 meters (approximately).

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.

1 mile = 1,609.344 meters (exactly).
