How Many Acres in a Square Mile?

A square mile is a unit of area used to measure land. It is a square with sides that are each one mile long. In contrast, an acre is a unit of area that measures 43,560 square feet or 4,840 square yards. While these two units are both used to measure land area, they differ in their exact measurements.

Conversion Between Square Miles and Acres

To convert between square miles and acres, we can use the following formula:1 square mile = 640 acresThis means that if you have a piece of land that measures one square mile, it would be equivalent to 640 acres. Conversely, if you have 640 acres of land, it would be equivalent to one square mile.To convert any number of square miles to acres, simply multiply the number of square miles by 640. For example:

• 2 square miles = 2 × 640 = 1,280 acres
• 5 square miles = 5 × 640 = 3,200 acres
• 10 square miles = 10 × 640 = 6,400 acres

And to convert acres to square miles, divide the number of acres by 640. For example:

• 1,000 acres = 1,000 ÷ 640 = 1.5625 square miles
• 5,000 acres = 5,000 ÷ 640 = 7.8125 square miles
• 10,000 acres = 10,000 ÷ 640 = 15.625 square miles
