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.
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.
