It is (or should be) given by the key.
The scale.
To determine the length of the object in the drawing, use the scale of 3 inches for every 4 feet. First, find the ratio of the actual length to the scale length: ( 24 \text{ ft} \div 4 \text{ ft} = 6 ). Then, multiply this ratio by the scale length: ( 6 \times 3 \text{ in} = 18 \text{ in} ). Therefore, the length of the object in the drawing is 18 inches.
It's called the "scale."
# is the ratio of the demensions in the drawing to the corresponding actual dimensions. The scale factor for a scale drawing is the ratio of the dimensions in the drawing to the corresponding acual bimensions.

a scale
The scale.
The scale factor of a scale drawing is the ratio of any length in the drawing to the true corresponding length in the "real" object.
It's called the "scale."
# is the ratio of the demensions in the drawing to the corresponding actual dimensions. The scale factor for a scale drawing is the ratio of the dimensions in the drawing to the corresponding acual bimensions.
The scale indicates how many units of length of the actual object are represented by each unit of length in the drawing.
It is the scale ratio or scale factor

SCALE - S. Balaji Sreenivas
A scale drawing makes it easier to visualize and work with objects of systems that are very large or very small. The key decision is determining the scale, i.e., the ratio between the dimensions of the object and the scale drawing.
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.
