Circular Inch
A circular inch is a unit of area measurement representing the area of a circle with a diameter of one inch.
History/Origin
The circular inch originated as a specialized measurement in fields requiring precise circular area calculations, but it is not widely used in standard measurement systems and has limited historical adoption.
Current Use
Today, the circular inch is primarily used in niche applications such as engineering and manufacturing where circular area measurements are relevant, but it remains a rarely used unit outside specialized contexts.
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.
