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.
Square Chain
A square chain (ch^2) is a unit of area equal to the area of a square with sides measuring one chain (66 feet) each, equivalent to 4356 square feet.
History/Origin
The square chain originated in land measurement practices in England, particularly used in surveying and land division during the 19th century, especially in the context of the Imperial system.
Current Use
Today, the square chain is largely obsolete and rarely used outside historical or land survey contexts; modern measurements typically employ acres or square meters.
