The ratio is marked at the left end of the scale. For example, the scale of 1:50 means that 1 mm on the drawing represents 50 mm on the object. This means that the object is 50 times larger than the drawing of it. An object 450 mm long would be represented by a line 9 mm long (450 mm/50).

Concept: A drawing at a scale of 1:50 means that one unit of measurement on the drawing represents 50 units of the actual object being represented. In this case, 3 cm on the drawing corresponds to one and a half meters in real life.

The 1:50 scale is a widely used scale for diecast car models. It is commonly used by collectors and enthusiasts who appreciate highly detailed replicas of real cars.

1:32 scale is a traditional scale for models and miniatures, in which one unit (such as an inch or a centimeter) on the model represents 32 units on the actual object. It is also known as "three-eighths scale", since 3⁄8 inch represents a foot.
