Quick Scoop

  • 1 acre = 0.0015625 square miles (the flip side of the same conversion).

Think of a square mile as a big square, 1 mile on each side. If you divided that large square evenly into 640 smaller equal plots, each of those plots would be 1 acre in size.

So any time you see land listed in square miles, you can multiply by 640 to get acres, and divide acres by 640 to get square miles.

TL;DR: 1 square mile = 640 acres, every time.
