A complete sparse ruler is called maximal if there is no complete sparse ruler of greater length with marks. Complete minimal rulers of length 135 and 136 require one more mark than those of lengths 124-134, 137 and 138. A sparse ruler is called optimal if it is both minimal and maximal.
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.

This is a list of units of measurement based on human body parts or the attributes and abilities of humans (anthropometric units). It does not include derived units further unless they are also themselves human-based. These units are thus considered to be human scale and anthropocentric.
The ruler the simplest kind of length measurement tool: lengths are defined by printed marks or engravings on a stick. The metre was initially defined using a ruler before more accurate methods became available. Gauge blocks are a common method for precise measurement or calibration of measurement tools.
The Bills were eventually ruled short and turned the ball over on downs. The Chiefs subsequently scored a touchdown five plays later that gave them a one-score lead.
Wegstunde – 'Way's hour', one hours travel (by foot), used up to the 18th century. In Germany 1 ⁄ 2 Meile or 3.71 km, in Switzerland 16000 feet or 4.8 km; Meile – 'Mile', a German geographische Meile or Gemeine deutsche Meile was defined as 7.420 km, but there were a wealth of variants: Anhalt – 7532 m
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.
