Attojoule
An attojoule (aJ) is a unit of energy equal to 10^-18 joules.
History/Origin
The attojoule was introduced as part of the SI prefixes to measure extremely small amounts of energy, particularly in fields like nanotechnology and quantum physics, as the need to quantify very tiny energy scales grew.
Current Use
The attojoule is used in scientific research to measure minute energy quantities, such as in nanotechnology, quantum computing, and molecular biology, where energies involved are extremely small.
Gigaton
A gigaton (Gton) is a unit of mass equal to one billion metric tons or 10^9 metric tons.
History/Origin
The gigaton has been used in scientific and environmental contexts to quantify large-scale phenomena such as greenhouse gas emissions and ice mass changes, gaining prominence in climate science discussions since the late 20th century.
Current Use
Currently, the gigaton is used to measure and communicate large quantities of emissions, such as annual carbon dioxide emissions from countries or sectors, and to assess changes in global ice mass and other large-scale environmental metrics.
