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.
The 1:64 scale is a traditional scale for models and miniatures, in which one unit (such as an inch or a centimeter) on the model represents 64 units on the actual object. It is also known as the "three-sixteenths scale" since 3/16 of an inch represents one foot.

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. [1]
The first reading is from the scale on pointer B where it crosses the topmost spiral of the helical scale on the cylinder. The second reading is from the scale at the top circumference of cylinder C where it crosses the left edge of pointer B. The sum of the readings provides the mantissa of the log of the value.

[1] [2] [3] Many types of calipers permit reading out a measurement on a ruled scale, a dial, or an electronic digital display. A common association is to calipers using a sliding vernier scale. Some calipers can be as simple as a compass with inward or outward-facing points, but with no scale (measurement indication).
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.
Now the most prolific [11] small scale (i.e. less than 1:35) for plastic injection armoured fighting vehicle (AFV) models, and also plastic model figurines and scale model vehicles and aircraft by companies such as Airfix. 1:65: 4.689 mm Ships, die-cast cars. Similar to 1:64. 1:64: 4.763 mm Ships, die-cast cars.
In 1885, French mathematician Édouard Lucas posed an arithmetic problem during a session of the Académie française.Genaille, already known for having invented a number of arithmetic tools, created his rulers in the course of solving the problem.
