What is the scale? What is scale =

Scale is the ratio of the length of a line segment on the map to the actual length of the corresponding line segment on the ground. Scale = the ratio of the distance on the map to the actual distance. (Scale = distance on map: actual distance).

Proportional formula:

Map distance = actual distance × scale

Actual distance = distance on map/scale.

Proportion = distance on the map ÷ actual distance. (Pay attention to the conversion between units in proportion calculation)

( 1km = 1km = 1x 1000m = 1x 100000cm)

Unit conversion: centimeters on the map, kilometers on the spot, centimeters for kilometers, and five zeros; Kilometers represent centimeters, and two zeros are added to thousands.

Extended data:

The national surveying and mapping department will allocate 1: 5000,1:1: 25000, 1: 50000, 1: 250000. These include:

1, large-scale topographic map: 1: 5000 to 1: 1 10,000 topographic map;

2. Medium-scale topographic maps: 1: 250000 and 1: 500000 topographic maps;

3. Small-scale topographic map:1:110,000 topographic map.

Measures in life:

Such as maps, cartography, surveying, fields, aviation, highways, navigation and architecture.
