Watt-Second
A watt-second (W·s) is a unit of energy equivalent to one joule, representing the amount of energy transferred or converted when one watt of power is applied for one second.
History/Origin
The watt-second originated from the SI system of units, where the watt (W) is the SI derived unit of power, and the second (s) is the SI base unit of time. It has been used historically in physics and engineering to quantify energy, especially in contexts where energy transfer occurs over short durations.
Current Use
The watt-second is primarily used in scientific and engineering contexts to measure small amounts of energy, such as in electrical and mechanical systems. It is often replaced by the joule in modern applications but remains a recognized unit within the energy converter category.
Calorie (Th)
The calorie (th) is a unit of energy used to quantify the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie (th) was historically used in the context of thermochemistry and nutrition, originating from the calorie concept in the 19th century. It has largely been replaced by the joule in scientific contexts but remains in common use in some regions and fields.
Current Use
Today, the calorie (th) is primarily used in nutrition labeling and food energy measurements, especially in regions where the thermochemical calorie is still recognized, although the joule is the SI standard.
