Square Mil
A square mil is a unit of area equal to the area of a square with sides measuring one mil (thousandth of an inch).
History/Origin
The square mil has been used primarily in engineering and manufacturing to measure very small areas, especially in fields like electronics and materials science, where precision at a microscopic scale is required.
Current Use
Today, the square mil is mainly used in the electronics industry to specify the cross-sectional area of wires and conductors, as well as in materials science for measuring tiny surface areas.
Square Rod (Us Survey)
A square rod (US survey) is a unit of area equal to the area of a square with sides measuring one rod (16.5 feet) each, used primarily in land measurement.
History/Origin
The square rod originated from the traditional land measurement system in the United States, particularly in surveying and real estate, where the rod was a common unit of length. It has been used historically for measuring plots of land, especially in rural and agricultural contexts.
Current Use
Today, the square rod (US survey) is largely obsolete and replaced by more modern units like acres. However, it may still be encountered in historical land records and surveying documents.
