Convert joule/second to kilocalorie (th)/hour
Please provide values below to convert joule/second [J/s] to kilocalorie (th)/hour [kcal(th)/h], or Convert kilocalorie (th)/hour to joule/second.
1 J/s = 0.860420651741 kcal(th)/h. To convert joule/second to kilocalorie (th)/hour, multiply the value by 0.860420651741; to go the other way, divide by it (1 kcal(th)/h = 1.16222222 J/s). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Joule/second
The joule per second (J/s) is a unit of power representing the rate at which energy is transferred or converted, equivalent to one watt.
History/Origin
The joule per second has been used as a measure of power since the adoption of the SI system, where the watt (W) became the standard unit of power, with 1 J/s = 1 W.
Current Use
J/s is primarily used in scientific and engineering contexts to quantify power, especially in physics and electrical engineering, often interchangeably with watts.
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.
