Picogram
A picogram (pg) is a unit of mass equal to one trillionth (10^-12) of a gram.
History/Origin
The picogram was introduced as part of the metric system to measure extremely small masses, especially in scientific and laboratory contexts, as a subdivision of the gram in the SI unit system.
Current Use
Picograms are used in scientific fields such as biology, chemistry, and physics to measure very small quantities of substances, including DNA, proteins, and other microscopic materials.
Grain
A grain is a unit of mass traditionally used to measure small quantities, primarily in the context of precious metals, pharmaceuticals, and firearms.
History/Origin
The grain dates back to ancient times and was originally based on the weight of a single seed of a cereal grain, such as barley. It has been used since the Middle Ages and was standardized in the apothecaries' system.
Current Use
Today, the grain is mainly used in the measurement of bullets, gunpowder, and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.
