Square Nanometer [nm²]


A square nanometer (nm²) is a unit of area equal to a square with sides 1 nanometer long (1 nm = 1 billionth of a meter, or 10⁻⁹ m).

It’s used to measure extremely tiny areas, like the surface of molecules or nanomaterials.

1 nm² = 1 × 10⁻¹⁸ 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.
