In old days (long before you and me) an acre was the amount of land a man

adopt metric. Or not. Mind you, we did here in Canada 20+ (30?) years ago
and we still talk about miles, acres, pounds and inches. Instead of a metric
or imperial system we have a bit of both.

Let's see, there's 640 acres to a
section, and a section of
land is 1 mile by 1 mile, or a 1 mile square.
Incredible, those units !
So a square piece of one acre would have a size of
1 mile / sqrt(640). That square root is not an integer.
Is this the definition of 1 acre ?
