An adult human foot is about 28 cm (11 in) long. The decimetre ( SI symbol: dm ) is a unit of length in the metric system equal to 10 −1 metres ( 1 / 10 m = 0.1 m ). To help compare different orders of magnitude , this section lists lengths between 10 centimeters and 100 centimeters (10 −1 meter and 1 meter).

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.
For example, one inch measured from a drawing with a scale of "one-inch-to-the-foot" is equivalent to one foot in the real world (a scale of 1:12)....one inch measured from a drawing with a scale of "two-inches-to-the-foot" is equivalent to six inches in the real world (a scale of 1:6). It is not to be confused with a true unitless ratio.
