An architect's scale is a specialized ruler designed to facilitate the drafting and measuring of architectural drawings, such as floor plans and Multi-view orthographic projections. Because the scale of such drawings is often smaller than life-size, an architect's scale features multiple units of length and proportional length increments.

The 1:64 scale originated by halving the common 1:32 scale, which was known as "standard size" in some hobbies.. This smaller scale became successful because of its relative size in comparison to other toys, the fact that it is a derivative of the 1/16 scale, and because small hands easily hold them. [1]
Unit and value marks — as on a ruler or number line; Congruence notation in geometry — as on a geometric figure; Graphed points — as on a graph; Hatch marks are frequently used as an abbreviation of some common units of measurement. In regard to distance, a single hatch mark indicates feet, and two hatch marks indicate inches.
A ruler with two linear scales: the metric and imperial.It includes shorter minor graduations and longer major graduations. A graduation is a marking used to indicate points on a visual scale, which can be present on a container, a measuring device, or the axes of a line plot, usually one of many along a line or curve, each in the form of short line segments perpendicular to the line or curve.
Canonically, and originally, in 1958 when Smoot was a Lambda Chi Alpha pledge at MIT (class of 1962), the bridge was measured to be 364.4 Smoots, plus or minus one ear, using Mr. Smoot himself as a ruler. [17] At the time, Smoot was 5 feet, 7 inches, or 170 cm, tall. [18] Google Earth and Google Calculator include the smoot as a unit of ...
