The map scale is published in the map legend. The is provided as a proportion of customs on the map corresponding to inches, feet, or mile on the ground. Because that example, a map scale indicating a ratio of 1:24,000 (in/in), method that because that every 1 inch on the map, 24,000 inches have been spanned on the ground. Ground ranges on maps space usually provided in feet or miles.
You are watching: A map scale of 1 24000 means that
Map scale Conversion Factors
Table 5.1. Map scale Conversion Factors
Example 1- convert the map range of 1:24,000 (in/in) to (in/ft).Step 1.Set up the cancellation table so all systems will cancel, other than the wanted unit, ft/in.
USING THE amendment ACREAGE net (TRANSPARENCY)
To usage the acreage network transparency, follow these steps:
Map Scales and Equivalents
Table 5.2 Acreage grid Overlay, Map Scales, and Equivalents.Place the acreage net transparency over the area to be measured.Count dots within the sketched area. Count every various other dot once dots fall on the border line.Multiply the total variety of dots by the conversion element on the map range to determine the total acreage. (See Table 5.2.)Example 3b- making use of the details in example 3a, discover the ground street in chains, miles, and inches.Step 1.Set increase the cancellation table for this reason all systems will cancel, except the desired unit, chains.
Step 2.Set increase the cancellation table for this reason all systems will cancel, except the wanted unit, miles.
Occasionally, a map may not carry out a scale. The scale can be calculate by discovering the distance between two point out on the map, and also measuring the street on the map. Also, if a map has section lines, the distance in between section currently is frequently 1 mile.Example 4- The street between suggest A and B is 6 inch on the map. The well-known ground distance is 3,600 feet. What is the scale in devices of inches/foot?
map scale = recognized distance / measure distance
Rearrange state by multiplying each side by the measure up distance and also dividing every side through the mapscale.
measured street = recognized distance / map scaleStep 1.Set increase the cancellation table therefore all devices will cancel, except the desired unit, feet.
