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.
Sabin
The sabin is a unit of luminous intensity used to measure the brightness of light sources, specifically in photometry.
History/Origin
Named after the French physiologist Charles-Édouard Guillaume, the sabin was introduced in the early 20th century as a unit to quantify luminous intensity, primarily used in scientific and engineering contexts related to light measurement.
Current Use
The sabin is rarely used today; it has been largely replaced by the candela in the International System of Units (SI). However, it may still appear in historical data or specialized fields related to light measurement.
