The answer depends on what aspect of the scale drawing you wish to calculate.
# 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.
1cm = 78.6
Not all drawings are done to scale, sketches of buildings and people for instance. However if it is a technical drawing the draughtsman/woman will state on the drawing the scale used.
a scale drawing.
Drawing to scale means to draw real objects in their accurate sizes except they are reduced. A house plan is a common item that is drawn to scale. Model cars are another example of drawing to scale. The item is in proportion but smaller.
The scale on a drawing represents the ratio of the size of the drawing to the actual size of the object. It must be considered to ensure accurate measurements and proportions in the drawing. Using the correct scale helps convey the information clearly and allows others to interpret the drawing accurately.
It shows how it relates to the actual house. Without scale, you would need as much paper as there is house. Example: a 30 foot house with the scale of 30:1 would be drawn as being 1 foot tall.

It shows the constant of proportionality between the scale drawing and the real-life object.
it depends of the scale of the drawing
