Convert calorie (th)/hour to femtowatt
Please provide values below to convert calorie (th)/hour [cal(th)/h] to femtowatt [fW], or Convert femtowatt to calorie (th)/hour.
1 cal(th)/h = 1.1622e+15 fW. To convert calorie (th)/hour to femtowatt, multiply the value by 1.1622e+15; to go the other way, divide by it (1 fW = 8.6042e-16 cal(th)/h). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 cal(th)/h = 1.1622e+15 fW
- 1 fW = 8.6042e-16 cal(th)/h
- 10 cal(th)/h = 1.1622e+16 fW
- 100 cal(th)/h = 1.1622e+17 fW
How to Convert Calorie (Th)/hour to Femtowatt
1 cal(th)/h = 1.16222222e+15 fW

Calorie (Th)/hour
Calorie per hour (cal(th)/h) is a unit of power representing the amount of heat energy in calories transferred or used per hour.
History/Origin
The calorie, originally defined as the amount of heat needed to raise the temperature of 1 gram of water by 1°C, has been used in various contexts including nutrition and physics. The 'th' denotes the thermochemical calorie, an older standard. The unit cal(th)/h has been used historically in thermodynamics and heat transfer measurements.
Current Use
Today, cal(th)/h is rarely used in modern scientific contexts, having been largely replaced by SI units like watts. However, it may still appear in legacy systems or specialized fields involving heat transfer calculations.
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.
