Current Use
Today, the pennyweight is primarily used in the jewelry trade and precious metals markets to specify weights of gold, silver, and gemstones, especially in the United States and in contexts where precise measurement of small quantities is required.
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.
