the corresponding measurement of the original figure. A scale factor is a number used as a multiplier in scaling. (Units are not mentioned in a scale factor.) Example: A sidewalk 20 feet long is drawn on a map as 4 inches in length.
A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount (called the scale). The scale is shown as the length in the drawing, then a colon (":"), then the matching length on the real thing.
