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 Dekameter
A square dekameter (dam²) is a unit of area equal to the area of a square with sides measuring one dekameter (10 meters).
History/Origin
The square dekameter originated from the metric system, which was developed in the late 18th century to standardize measurements. It is derived from the dekameter, a metric unit of length, and used primarily in contexts requiring larger area measurements.
Current Use
The square dekameter is rarely used in modern practice, having been largely replaced by the hectare (ha) for land measurement. It may still be encountered in scientific or educational contexts involving metric area conversions.
