Circular Mil
A circular mil is a unit of area used to measure the cross-sectional size of wires, representing the area of a circle with a diameter of one mil (one thousandth of an inch).
History/Origin
The circular mil originated in the electrical industry to specify wire sizes before the adoption of metric units. It has been a standard measurement in North America for wire gauge sizes for many decades.
Current Use
Circular mils are still used today in the electrical industry to specify wire cross-sectional areas, especially in North America, although metric units are increasingly common.
Square Hectometer
A square hectometer (hm^2) is a unit of area equal to the area of a square with sides of one hectometer (100 meters).
History/Origin
The square hectometer originated from the metric system's adoption, where 'hecto' denotes a factor of 100. It has been used primarily in scientific and geographical contexts to measure large areas.
Current Use
The square hectometer is rarely used in everyday measurements but is occasionally employed in scientific, environmental, and geographical studies to express large land or area measurements.
