It depends on the scale of the map. Topographic map series offer a consistent scale across the series, usually an even number such as 1:24,000, 1:50,000, 1:100,000, etc. Different countries offer different topographic series scales.
For reference, 1:63360 is equivalent to one inch to the mile, so at that scale, a square inch is equal to a square mile.
Miles measures distance. Square miles measures area. therefore, you can not compare the two.
A mile is the length of a line, square miles are the measure of area, typically of a square or rectangle
1 square mile = 640 acres 4 acres = 4/640 = 1/160 square mile = 0.00625 square mile = (5/8 of 1%) of a sq mi
AnswerThere is no formula that equates one acre to one square mile. At least there is no TRUE formula that does so. I mean I could type 1 acre = 1 mi2, and that would be a formula, but it would not be true. Because one acre is NOT equal to one square mile, and never will be. In fact, it takes 640 acres to equal a square mile.
A scale of 1 inch representing 1 mile on a map means that for every inch on the map, the distance it represents in the real world is 1 mile. This scale allows users to easily calculate real-world distances by measuring distances on the map.
A commonly used scale on a topographic map is 1:24,000
There are 640 acres in 1 square mile. So (1/2 mile)*(1/4 mile) = 1/8 square mile, or:(1/8 square mile)*(640 acre/square mile) = 80 acres
Miles measures distance. Square miles measures area. therefore, you can not compare the two.
A square with 1/2 mile sides has an area of 1/4 square mile.
1 acre = 0.0015625 square mile 1 square mile = 640 acres
1 square mile is 27,878,400 square feet.
1 square mile = 27,878,400 square feet.
1 (square mile) = 2.58998811 square kilometers1 (square kilometer) = 0.386102159 square mile
A square mile is an area measurement, not a specific shape. They could be just about anything, as long as they multiply together to make one square mile. 1 mile by 1 mile is a square mile. Two miles by half a mile is a square mile. 1 foot by 5280 miles is a square mile. This means that 8 square miles can be 2 miles by 4 miles or 1 mile by 8 miles.
There are 40 acres in 1/16th of a square mile 1 square mile = 640 acres
To measure distance using a topographic map, you can use the map's scale. First, determine the scale of the map, such as 1:24,000. Then, use a ruler to measure the distance on the map between two points that you want to calculate the actual distance for. Convert the measured distance on the map to the actual distance using the map scale.
27,878,400 square feet equal 1 square mile.
