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 Foot (US Survey)


The square foot (US survey) is a unit of area based on the US survey foot, which is slightly longer than the international foot. It is mainly used in land surveying and mapping in the United States.



  • 1 US survey foot = 1200⁄3937 meters (approximately 0.3048006096 m)



  • 1 square foot (US survey) ≈ 0.0929034116 m²



This unit helps maintain consistency in US land measurements, especially in legal and cadastral contexts.
