The Fuller calculator, sometimes called Fuller's cylindrical slide rule, is a cylindrical slide rule with a helical main scale taking 50 turns around the cylinder. This creates an instrument of considerable precision – it is equivalent to a traditional slide rule 25.40 metres (1,000 inches) long.

Each ruler's scale has graduations labeled with precomputed outputs of various mathematical functions, acting as a lookup table that maps from position on the ruler as each function's input. Calculations that can be reduced to simple addition or subtraction using those precomputed functions can be solved by aligning the two rulers and reading ...
A Smith chart to calculate electrical impedance with no values plotted; although not a nomogram, it is based on similar principles. Like a slide rule, a nomogram is a graphical analog computation device. Also like a slide rule, its accuracy is limited by the precision with which physical markings can be drawn, reproduced, viewed, and aligned.
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.
Rulers may also be used as a support for separate special rulers and letter templates. The rules are replaceable and they can be for example scale-rules. Drawing apparatus has evolved from a drawing board mounted parallel ruler and a pantograph, which is a device used for copying objects in an adjustable ratio of sizes.
The Speed Square tool is an isosceles right triangle with a ruler on one equal side and a fence on the other. It is marked with the word Pivot at the right angle point and displays Degrees on its hypotenuse, Common and Hip/Val markings on its midsection. Degree indicates the angle in degrees from 0° to 90°.
In the United States, the marking is usually in customary units (three feet 3 + 3 ⁄ 8 inches with inch and fractional inch). Hybrid measures bearing customary markings on one side and metric units on the other also exist and are sometimes referred to as yardsticks, metre-whesticks [citation needed] or "metre rulers". The spelling meter vs ...
