About these units

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).

Foot (ft)

US & ImperialCurrent unit

12 inches. Defined as exactly 0.3048 meters. Still the standard unit for height, altitude in aviation and room dimensions in the US and UK.

Human anatomy supplied the idea: an adult foot is roughly 15 percent of body height. Ancient cultures turned that into standards, but not the same one. The Greek pous was about 302 mm, the standard Roman pes about 295.7 mm, and a Harappan foot of about 335 mm has been reported from the Indus Valley. Historically, a foot fell somewhere between about 250 and 335 mm. Charlemagne tried to standardize units around 790 with little lasting success, and in 1593 English law fixed the statute mile at 5,280 feet.

The modern foot dates from the 1959 International Yard and Pound Agreement, which defined the yard as exactly 0.9144 meter and so the foot as exactly 0.3048 meter; the UK adopted it on 1 January 1964. The US survey foot, defined in 1893 as 1200/3937 meter, was deprecated on 31 December 2022. Feet remain in everyday use for height and rooms in the US, and ISO shipping containers are defined in them. Aviation altitudes use them too: flight level 330 means 33,000 feet.

1 foot = 0.3048 meters (exactly).
