How many square miles is in 20 acres?

Answer 1

There is no equivalence.

A foot is a measure of length or distance in 1-dimensional space while an acre is a measure of area in 2-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid without some addition information.

Answer 2

Miles are a unit of length whereas acres are a unit of area.

As such your question makes no sense.

I'll assume you meant:

How many square miles are in twenty acres?

640 acres = 1 square miles

⇒ 20 acres = 20 ÷ 640 square miles

= 1/32 square miles

= 0.03125 square miles

Answer 3

The question, as stated, cannot be answered sensibly. An acre is a measure of area, with dimensions [L2], so that an acre square is a measure of "area", in 4-dimensional hyperspace, with dimensions [L4]! A foot, by contrast, is a measure of distance, with dimensions [L].

The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.

Answer 4

Twenty acres is the same length as 1390 yards. It is also equal in length to 4,170 feet, or 1,650 feet less than a mile.

Answer 5

There are 0.03125 square miles in 20 acres.

Answer 6

20 acres = 871,200 square feet

Answer 7

20 acres = 871,200ft²

Answer 8

20 acres is 871,200 square feet.

Answer 9

20 acres = 0.03125 square mile
