How big is an acre?
Acres can be any shape but they are always 43,560 square feet in area !
Most Canadian farmers did not adopt hectares when the metric system arrived
In western Canada land was divided in 1 mile square parcels called sections.
There are 43,560 square feet in 1 acre, there are 640 acres in 1 section...
I have heard of a Hector on a prairie farm but I think he was someones Uncle !
