What is a Microgram and a Stone?
A microgram is a unit of mass in the metric system equal to one millionth (1/1,000,000) of a gram, or one thousandth (1/1,000) of a milligram. It is often denoted by the symbol µg.
The stone (st) is a unit of mass in the British imperial system, defined as exactly 14 avoirdupois pounds. This is equivalent to approximately 6.35 kilograms.
Note: The Microgram is part of the metric (SI) system, primarily used globally in science and trade. The Stone belongs to the imperial/US customary system.
History of the Microgram and Stone
The microgram is derived from the gram, a base unit in early metric systems defined in the late 18th century. The prefix "micro-" indicates a factor of 10⁻⁶.
The stone has historical roots in trade, where actual stones were used as weights. Its value varied significantly by commodity and region before being standardized at 14 pounds in Britain for general purposes.
