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.
Kilocalorie (Th)/hour
A kilocalorie (th)/hour (kcal(th)/h) is a unit of power representing the rate at which energy in kilocalories per hour is transferred or converted.
History/Origin
The kilocalorie, often used in nutrition and energy measurement, has been adapted into various units including the thermochemical kilocalorie (kcal(th)). Its use in power measurement, such as kcal(th)/h, is primarily for specialized scientific and engineering applications, integrating energy units with time to express power.
Current Use
The kcal(th)/h unit is used in contexts requiring the measurement of energy transfer rates in thermochemical terms, such as in thermal engineering, calorimetry, and energy efficiency assessments where energy flow is expressed in kilocalories per hour.
