Actual Distance Formula
The following formula is used to calculate the Actual Distance.
AD = MD / (1/X)
- Where AD is the Actual Distance
- X is the map scale (1:X)
- MD is the measured distance
To calculate the actual distance, divide the map scale by the measured distance.
How to Calculate Actual Distance?
The following example problems outline how to calculate Actual Distance.
Example Problem #1:
- First, determine the map scale (1:X).
- The map scale (1:X) is given as: 50,000.
- Next, determine the measured distance.
- The measured distance is provided as: 3.
- Finally, calculate the Actual Distance using the equation above:
AD = MD / (1/X)
The values given above are inserted into the equation below and the solution is calculated:
AD = 3 / (1/50,000) = 150,000
Example Problem #2:
For this problem, the variables needed are provided below:
map scale (1:X) = 2,500
measured distance = 10
This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
AD = MD / (1/X) = ?
