English: a ruler from 0 to 1 inch (in.) in 1/32 inch divisions below the line and 1/2 millimetre (mm) divisions above the line to give a visual representation of the approximations. Principally designed to help visually determine if a metric or imperial drill bit will suffice.
A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length; two common examples are an architect's scale and engineer's scale.In scientific and engineering terminology, a device to measure linear distance and create proportional linear measurements is called a scale.

A ruler, sometimes called a rule, scale or a line gauge or metre/meter stick, is an instrument used to make length measurements, whereby a length is read from a series of markings called "rules" along an edge of the device.

Demonstration of 2 / 3 via a zero-value game. A slight rearrangement of the series reads + + =. The series has the form of a positive integer plus a series containing every negative power of two with either a positive or negative sign, so it can be translated into the infinite blue-red Hackenbush string that represents the surreal number 1 / 3 :
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.
25.4 μm A thousandth of an inch is a derived unit of length in a system of units using inches . Equal to 1 ⁄ 1000 of an inch , a thousandth is commonly called a thou / ˈ θ aʊ / (used for both singular and plural) or, particularly in North America, a mil (plural mils ).
