Teragram
A teragram (Tg) is a unit of mass equal to one trillion grams or 10^12 grams.
History/Origin
The teragram is part of the metric system and was introduced as a larger unit for measuring very large masses, especially in scientific contexts, to facilitate easier expression of large quantities.
Current Use
Teragrams are used primarily in scientific fields such as environmental science, geology, and astronomy to quantify large masses, like global emissions or mineral deposits.
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.
