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.
Picogram
A picogram (pg) is a unit of mass equal to one trillionth (10^-12) of a gram.
History/Origin
The picogram was introduced as part of the metric system to measure extremely small masses, especially in scientific and laboratory contexts, as a subdivision of the gram in the SI unit system.
Current Use
Picograms are used in scientific fields such as biology, chemistry, and physics to measure very small quantities of substances, including DNA, proteins, and other microscopic materials.
