What is a square chain?
A square chain is the area of a square one surveyor's chain — 66 feet — on each side: 404.68564224 square meters.
The chain was the surveyor's basic measuring tool, and its square fits neatly into the old land system: ten square chains make exactly one acre.
In writing, the square chain is usually shortened to "ch²". One square chain is 404.6856422 square meters, and that ratio is what every number on this page is built from.
