Picowatt
A picowatt (pW) is a unit of power equal to one trillionth (10^-12) of a watt.
History/Origin
The picowatt was introduced as part of the SI prefixes to measure extremely small amounts of power, especially in scientific and technological contexts, following the standardization of the watt as the SI unit of power.
Current Use
Picowatts are used in fields such as electronics, physics, and biology to quantify very low power levels, including in sensor measurements, quantum physics, and nanotechnology applications.
Calorie (It)/hour
Calorie per hour (cal/h) is a unit of power that measures the rate at which energy in calories is transferred or consumed over time.
History/Origin
The calorie has been used historically in nutrition and thermodynamics to quantify energy. The cal/h unit emerged in contexts where energy transfer rates were expressed in calories per hour, particularly in heating and metabolic studies.
Current Use
Cal/h is used in specific scientific and engineering applications, such as measuring heat transfer rates, metabolic rates, and in some thermal engineering contexts, although it is less common than SI units like watts.
