About these units
Mile (US Survey) (mi (US))
The US Survey Mile equals 5,280 US Survey Feet (~1,609.347 meters). Slightly longer than the international mile due to the use of the US survey foot, it has been essential for mapping, transportation planning, and geodetic calculations in the United States. Surveyors and engineers relied on the US survey mile to ensure precise alignment of property boundaries, railroad tracks, and infrastructure projects. Over long distances, even small differences between the US survey and international mile can accumulate significantly, necessitating care in measurement. Though the international mile is now standard, the US survey mile remains important for interpreting historical maps, legal descriptions, and older engineering plans.
Twip (twip)
A twip is a twentieth of a point, equal to 1/1440 of an inch. This extremely small unit originated in computer typography, particularly in early word processors and GUI layout systems developed by Microsoft and Apple. Because digital screens and software-based layout engines require highly precise internal measurements, twips allowed consistent and resolution-independent positioning of graphical objects and text. Even when the actual pixel density of displays varied, twips provided a device-agnostic coordinate system. Twips remain particularly relevant in Microsoft technologies such as Visual Basic, Windows API interfaces, and the formatting of Office documents. Although ordinary users rarely encounter the term, twips form part of the invisible numerical infrastructure that ensures consistent layout across different computers, printers, and operating systems.
