Milligram
A milligram (mg) is a unit of mass equal to one thousandth of a gram.
History/Origin
The milligram has been used in scientific and medical contexts for precise measurement of small quantities, especially in pharmacology and chemistry, with its origins linked to the metric system established in the 18th century.
Current Use
Today, the milligram is widely used in pharmaceuticals, nutrition, and scientific research to measure small amounts of substances accurately.
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.
