Petagram
A petagram (Pg) is a unit of mass equal to 10^15 grams or one quadrillion grams.
History/Origin
The petagram was introduced as part of the metric system's prefixes to represent extremely large masses, following the adoption of the International System of Units (SI). It is derived from the prefix 'peta-' which denotes 10^15.
Current Use
The petagram is primarily used in scientific contexts to quantify very large masses, such as in astronomy and geology, but is rarely used in everyday measurements.
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.
