Square Rod (US Survey)


A square rod (US survey) is a unit of area based on the US survey foot and rod, used primarily in land surveying in the United States.



  • 1 US survey rod = 16.5 US survey feet (exactly 16.5 feet)

The US survey square rod is slightly different in exact length than the international measurement due to the foot definition but is essentially used the same way for land measurement.
