Which is larger a square mile or a square kilometer?

Answer 1

Acres and milesFirst, you should never say "square acre." The acre is a unit of area, so there is no need to qualify it with the word square. A mile, on the other hand, is a unit of distance, so the square mile is the unit of area.

Now, to answer the question.

There are 640 acres per square mile. So, the square mile is larger -- exactly 640 times as large.

Answer 2

To show the difference, we'll convert both to square feet:

• One square mile = 27,878,400 sq feet
• One square km = 10,763,910.4 sq feet

One square mile is larger.
