Nanogram
A nanogram (ng) is a unit of mass equal to one billionth (10^-9) of a gram.
History/Origin
The nanogram was introduced as part of the metric system to measure extremely small quantities, especially in scientific and medical fields, as the need for precise measurement of tiny masses grew with technological advancements.
Current Use
Nanograms are commonly used in scientific research, pharmaceuticals, and environmental testing to measure very small amounts of substances accurately.
Poundal
The poundal (pdl) is a unit of force in the foot-pound-second (FPS) system, defined as the force required to accelerate a one-pound mass at a rate of one foot per second squared.
History/Origin
The poundal was introduced in the 19th century as part of the FPS system of units, primarily used in engineering and physics before the widespread adoption of the SI system. It was designed to provide a consistent force unit based on imperial units.
Current Use
Today, the poundal is largely obsolete and rarely used outside of historical or specialized engineering contexts. It is mainly referenced for educational purposes or in discussions of imperial units, with the SI unit of force (newton) being the standard.
