Calorie (It)
The calorie (cal) is a unit of energy traditionally used to quantify the amount of heat required to raise the temperature of one gram of water by one degree Celsius at standard atmospheric pressure.
History/Origin
The calorie was originally defined in the 19th century as a unit of heat energy in thermodynamics. It has historically been used in nutrition and physics, but has largely been replaced by the joule in scientific contexts. The 'small calorie' (cal) is distinct from the 'large calorie' (kcal), which is commonly used in food energy labeling.
Current Use
Today, the calorie is primarily used in nutrition to measure the energy content of foods and beverages, although the SI unit of energy, the joule, is increasingly preferred in scientific and technical fields.
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.
