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 Decimeter
A square decimeter (dm^2) is a unit of area equal to the area of a square with sides of one decimeter (10 centimeters).
History/Origin
The square decimeter is derived from the decimeter, a metric unit of length, and has been used in metric measurements for expressing small to moderate areas, especially in scientific and engineering contexts since the adoption of the metric system.
Current Use
The square decimeter is used in various fields such as engineering, architecture, and science for measuring small surface areas, particularly where metric units are standard and precise measurements are required.
