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.
Nanogram
A nanogram (ng) is a unit of mass equal to one billionth (10^-9) of a gram.
History/Origin
The nanogram was introduced as part of the metric system to measure extremely small quantities, especially in scientific and medical fields, as the need for precise measurement of tiny masses grew with technological advancements.
Current Use
Nanograms are commonly used in scientific research, pharmaceuticals, and environmental testing to measure very small amounts of substances accurately.
