Megajoule
A megajoule (MJ) is a unit of energy equal to one million joules.
History/Origin
The megajoule was introduced as part of the metric system to measure large amounts of energy, especially in scientific and engineering contexts, aligning with the SI units established in the 20th century.
Current Use
The megajoule is used in fields such as physics, engineering, and energy industries to quantify large energy quantities, including in energy production, consumption, and scientific research.
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.
