About these units

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).

Twip (twip)

Typography & screenCurrent unit

1/20 of a point (1/1,440 inch). Used in the Rich Text Format specification and some software.

A contraction of twentieth of a point, the twip is a deliberately tiny unit meant for software that wants whole-number layout. Wikipedia gives it as 1/20 point, or 1/1440 inch, about 17.64 micrometers (0.01764 mm). That inch fraction only works if the point is the desktop publishing point of 1/72 inch, which is the definition the figure used here assumes.

Visual Basic 6 and earlier used twips as the default unit, and Microsoft's Rich Text Format uses them to exchange documents between platforms. OpenOffice.org and LibreOffice take it as their base length unit, and Symbian OS used it to scale bitmaps. Flash is a trap: its internal twips are really 1/20 of a logical pixel, which makes them three quarters of a true twip. Wikipedia's article also words the name two ways, as a twentieth of a point or of an inch point, and notes that it lacks citations.

1 twip = 0.00001763888889 meters (approximately).
