Representation of scale: What does this scale mean? It means 1:2000, how did it come about?

Scale = distance on the map: actual distance

How long is each small frame of your picture? You need to know the length

The names of the units of the distance on the map and the actual distance must be the same, for example: the distance of each cell on the map is one centimeter, and the actual distance is 1,000 meters (note that this is "meters", and the distance on the map is "centimeters"), so you have to put the actual distance unit into the unit of "centimeters". ), so to convert the actual distance unit, 1000 meters = 100000 centimeters, because scale = distance on the graph: actual distance, so, 1:100000 is the scale for this example.

Your this figure, if each small frame distance is one centimeter, and each small frame distance on the map represents the actual distance is 2 meters, the unit name is not uniform, so to unit conversion, 2 meters = 200 cm, because the scale = distance on the map: the actual distance, so, scale,1:200, I'm not sure that each small frame distance of your picture is 1 centimeter, you are still measuring it
