Earth's Mass
Earth's mass (M_earth) is a unit of mass representing the mass of the Earth, approximately 5.972 × 10^24 kilograms.
History/Origin
The concept of Earth's mass as a unit originated from scientific measurements of Earth's size and gravitational influence, becoming a standard reference in geophysics and astronomy.
Current Use
M_earth is used in scientific contexts to express planetary and astronomical masses, and in some cases, to compare the mass of other celestial bodies relative to Earth.
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.
