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.
Different lengths as in respect to the electromagnetic spectrum, measured by the metre and its derived scales.The microwave is between 1 meter to 1 millimeter.. The millimetre (international spelling; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the International System of Units (SI), equal to one thousandth of a metre, which is the SI base unit of length.
Although models of approximately this scale were being built as early as the 1930s, it was the founding of the Merioneth Railway Society just after the Second World War that marks the popularization of this scale. This set the light-hearted spirit of the 16 mm fraternity, where a sense of fun and whimsy often override more serious concerns.
Rulers come in two types according to the design of their edge. A ruler with a straight edge can be used with lead pencils and felt pens, whereas when a technical pen is used the edge must be grooved to prevent the spread of the ink. An architect's scale. A scale ruler is a scaled, three-edged ruler which has six different scales marked to its ...

The C-Thru Ruler Company is an American maker of measuring devices and specialized products for drafting, designing and drawing. The company was formed in 1939 in Bloomfield, Connecticut , [ 1 ] by Jennie R. Zachs, a schoolteacher, who saw the need for transparent measuring tools such as rulers , triangles , curves and protractors .
There is no requirement that a Golomb ruler be able to measure all distances up to its length, but if it does, it is called a perfect Golomb ruler. It has been proved that no perfect Golomb ruler exists for five or more marks. [3] A Golomb ruler is optimal if no shorter Golomb ruler of the same order exists. Creating Golomb rulers is easy, but ...
