Kilocalorie (Th)/second
A kilocalorie (th)/second (kcal(th)/s) is a unit of power representing the rate at which energy in kilocalories per second is transferred or converted.
History/Origin
The kilocalorie (th) is a traditional unit of energy used primarily in nutrition and thermodynamics, with 'th' indicating the thermochemical definition. Its use in power measurements, such as kcal(th)/s, is less common and primarily for specialized scientific contexts.
Current Use
The unit kcal(th)/s is rarely used in modern practice; power is more commonly expressed in watts. When used, it typically appears in scientific research involving energy transfer rates in thermochemical processes or specialized engineering applications.
Femtowatt
A femtowatt (fW) is a unit of power equal to 10^-15 watts, representing an extremely small amount of power.
History/Origin
The femtowatt was introduced as part of the SI prefixes to measure very small quantities of power, particularly in scientific and technological contexts, gaining recognition as the need to quantify minute power levels grew.
Current Use
Femtowatts are used in fields such as quantum physics, nanotechnology, and optical measurements, where precise measurement of extremely low power levels is required.
