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.
Ton (Long)
A long ton, also known as the imperial ton or UK ton, is a unit of weight equal to 2,240 pounds or 1,016.0469 kilograms.
History/Origin
The long ton originated in the United Kingdom as a standard measurement for large quantities of goods and materials, particularly in shipping and trade, during the 19th century. It was used alongside other imperial units before the adoption of the metric system.
Current Use
Today, the long ton is primarily used in the United Kingdom and some Commonwealth countries for measuring large quantities of freight, cargo, and in certain industrial contexts. It is less common internationally, having been largely replaced by the metric ton (tonne).
