In summary, the conversion factor from acres to miles is 0.0015625. This may differ from the answer in the book due to rounding errors or outdated information. However, this conversion factor can be used for any unit of land measurement in acres and any unit of length measurement in miles. The formula for converting acres to miles is: miles = acres x 0.0015625, or you can use the shortcut method of moving the decimal point three places to the left. For example, 10 acres would be equal to 0.01 miles using this method.

Homework Statement



Problem 2.2 An acre is defined such that 640 acres = 1 mi2. How many square meters
are in 1 acre?

Homework Equations



Solution From Table 2.1,
1 mi = 1.609 km = 1609 m
1 acre = 1/640 mi ^2

The Attempt at a Solution



My solution comes from wolfram alpha
4286 m^2

BOOK SOLUTION: 4.05 X 10^3 m^2

my on a calculator: 4045.13

So, why did wolfram get it wrong?
(1/604)(1609 m)^2 --> wolfram
