Square Kilometer
A square kilometer is a unit of area equal to the area of a square with sides measuring one kilometer each.
History/Origin
The square kilometer has been used as a standard unit of area measurement in the metric system since its adoption, primarily for measuring large land areas such as countries and regions.
Current Use
It is commonly used in geography, urban planning, and environmental studies to quantify land and area sizes, especially in contexts requiring large-scale measurements.
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.
