A scale is an ordered sequence of different values belonging to the same quality.
A scale is called a series of values or degrees that can be located within the same contingency or quantitative entity.
There are different types of scales. For example, a cartographic scale is that mathematical relationship between the real dimensions and the drawing on a plane, such as a map. Linked to this concept is that of a drawing or plan "to scale", that is, it is not made in its actual size but in a given proportion. This is except the legend reads "full scale", in which case the graphic or representation will respect the original proportions of the represented object.
When it is said that something is done "on a human scale" it means that it responds to the proportions of an average human being and that, therefore, in the case of a house or building, it is habitable by individuals.
Another type of scale is the musical scale, a group of notes that constitute a musical work. The economy of scale, to cite another example, is based on the production of goods in large quantities or, as they say, "on a large scale".
In addition to those scales, certain others have been named in response to their discoverer or ideologist. For example, the Pauling scale, which classifies the electronegativity of atoms, or the Richter or Mercalli scale, both with the ability to classify the magnitude of a system or earthquake. Or, that of Mohs, which qualifies the hardness of a substance.
Other common scales are those of temperature that are used in the production of thermometers, chromatic, for the classification and use of colors, for example in graphic design or in painting. There is also talk of scale or ladders to refer to the different instances that a professional can go through in the organization chart of a company or institution.
