Nanojoule
A nanojoule (nJ) is a unit of energy equal to one billionth (10^-9) of a joule.
History/Origin
The nanojoule was introduced as part of the SI unit system to measure very small amounts of energy, especially in scientific and technological contexts, with its usage becoming more common with advancements in nanotechnology and micro-scale energy measurements.
Current Use
Nanojoules are used in fields such as electronics, nanotechnology, and physics to quantify small energy quantities, including in the measurement of energy consumption in micro- and nano-scale devices.
Kilocalorie (Th)
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 unit to quantify heat energy, especially in nutrition and thermodynamics. It was widely adopted in the early 20th century for dietary energy measurement.
Current Use
Today, the kilocalorie is primarily used in nutrition to express the energy content of food and drinks, although it is often simply called a 'calorie' in everyday language.
