Convertir de Puntos < - > mm < - > cm < - > pixeles

In typography, a point is the smallest unit of measure, being a subdivision of the larger pica. It is commonly abbreviated as pt. The point has long been the usual unit for measuring font size and leading and other minute items on a printed page. The original printer's point, from the era of foundry metal typesetting and letter press printing, varied between 0.18 and 0.4 mm depending on various definitions of the foot. By the end of the 19th Century, it had settled to around 0.35 to 0.38 mm, depending on one’s geographical location.

In the late 1980s to the 1990s, the traditional point was supplanted by the desktop publishing point (also called the PostScript point), which was defined as 72 points to the inch (1 point = 1⁄72 inches = 25.4⁄72 mm = 0.3527 mm). In either system, there are 12 points to the pica. In metal type, the point size of the font described the size (height) of the metal body on which the typeface's characters were cast. In digital type, the body is now an imaginary design space, but is used as the basis from which the type is scaled (see em).

A measurement in picas is usually represented by placing a lower case p after the number, such as "10p" meaning "10 picas." Points are represented by placing the number of points after the p, such as 0p5 for "5 points," 6p2 for "6 picas and 2 points," or 1p1 for "13 points" which is converted to a mixed fraction of 1 pica and 1 point. (An alternate nomenclature is described in the pica article.)
