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 Meter
A square meter (m^2) is the SI unit of area, representing the area of a square with sides of one meter each.
History/Origin
The square meter was established as part of the International System of Units (SI) in 1960, based on the meter defined by the speed of light, and has since become the standard unit for measuring area in the metric system.
Current Use
The square meter is widely used in various fields such as real estate, architecture, land measurement, and engineering to quantify surface areas of spaces and objects.
