Convert femtowatt to kilocalorie (th)/hour
Please provide values below to convert femtowatt [fW] to kilocalorie (th)/hour [kcal(th)/h], or Convert kilocalorie (th)/hour to femtowatt.
1 fW = 8.6042e-16 kcal(th)/h. To convert femtowatt to kilocalorie (th)/hour, multiply the value by 8.6042e-16; to go the other way, divide by it (1 kcal(th)/h = 1.1622e+15 fW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 fW = 8.6042e-16 kcal(th)/h
- 1 kcal(th)/h = 1.1622e+15 fW
- 10 fW = 8.6042e-15 kcal(th)/h
- 100 fW = 8.6042e-14 kcal(th)/h
How to Convert Femtowatt to Kilocalorie (Th)/hour
1 fW = 8.60420651740766e-16 kcal(th)/h

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.
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.
