The metric scale uses the millimeter as its base measurement. Full size on the metric scale is shown as 1:1. Half scale is 1:2. It is helpful to think of this as one unit on the drawing equals two units on the object. A small object can be enlarged on the paper and drawn in 2:1 scale. This means the drawing of the object is twice as large as the object itself. Designers use an enlarged scale, such as double scale, on objects that are too small to draw full size with any meaningful detail. - https://sciencing.com/list-7612075-scales-used-technical-dra...
