Use is made of the surveyors units of measurement that define a foot as 1200 / 3937 meters. One survey square foot is 144 / 39.37 ^ 2 meters. Within an accuracy of (at least) 4 digits the square surveyor units of measurement are the same as the international measurement units where a square foot is (12 * .0254) ^ 2 meters.

Other measures: A square rod (square pole or square perch) is 272.25 square feet.
A square chain is a tenth of an acre (4356 square feet).
