What is a Gram and a Microgram?
The gram is a unit of mass in the metric system. Originally defined as the mass of one cubic centimeter of water at its maximum density, it is now defined as 1/1000 of a kilogram.
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.
Note: The Gram is part of the metric (SI) system, primarily used globally in science and trade. The Microgram belongs to the metric (SI) system.
History of the Gram and Microgram
Introduced in France after the French Revolution as part of the metric system. It became a fundamental unit for scientific measurement.
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.
