Square Millimeter [mm²]


A square millimeter (mm²) is a unit of area equal to a square with sides 1 millimeter long. It is used to measure very small surfaces, such as parts of mechanical components or electronic circuits.

1 mm² = 0.000001 m².


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)



  • 1 square rod (US survey) = 16.5 ft × 16.5 ft = 272.25 square feet ≈ 25.2929 m²



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.
