Scruple (Apothecary)
A scruple (s.ap) is an old unit of weight used in apothecary measurements, equivalent to 1.3 grains or approximately 1.3 grams.
History/Origin
The scruple originated in ancient Greece and was adopted into Roman and medieval European apothecary systems. It was historically used for measuring small quantities of medicinal substances and drugs.
Current Use
Today, the scruple is largely obsolete and replaced by metric units, but it is still referenced in historical contexts and traditional apothecary practices.
Attogram
An attogram (ag) is a unit of mass equal to 10^-18 grams, used to measure extremely small quantities.
History/Origin
The attogram was introduced as part of the metric system's expansion to include smaller units for scientific measurements, particularly in fields like nanotechnology and molecular biology, during the 20th century.
Current Use
Attograms are primarily used in scientific research to quantify very small masses, such as individual molecules or nanoparticles, and are part of the SI units for precise measurements in advanced scientific applications.
