A scale factor is a number that describes the ratio of the size of a scaled copy to the size of the original. To find the scale factor of a scaled copy, you can divide the length of the scaled copy by the length of the original. For example, if a scaled copy is twice as long as the original, then the scale factor is 2.
Scale factors are used in a variety of applications, including architecture, engineering, and manufacturing. They can be used to create scaled models of objects, to enlarge or reduce images, and to create maps and blueprints. Scale factors can also be used to convert between different units of measurement.
