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.
Kilocalorie (It)
A kilocalorie (kcal) is a unit of energy equal to 1,000 calories, commonly used to measure the energy content of food and beverages.
History/Origin
The kilocalorie originated in the 19th century as a measure of heat energy, primarily used in nutrition and thermodynamics. It became standard in dietary contexts to quantify food energy intake.
Current Use
Today, the kilocalorie is widely used in nutrition to express the energy content of foods and beverages, and in scientific contexts related to energy measurement in biological and physical systems.
