Show all calculations and units please.

Answer 1

Hecares are metric. Acres are imperial. I sold 3 acres of land, even Land Titles  couldn't do the conversion. I ended up with a strip of land 4 inches wide and about 300 yards long.

Answer 2

One acre is not 4 x 10^4 ft^2. It's 43560 ft^2. Therefore, the correct answer is:

1 ha * 10000 m^2/ha * (3.2808399)^2 ft^2 / m^2 * 1 acre / 43560 ft^2 = 2.471 acres

However, using your value for the size of an acre:

1 ha * 10000 m^2/ha * (3.2808399)^2 ft^2 / m^2 * 1 acre / 40000 ft^2 = 2.691 acres
