Convert joule/hour to kilojoule/second
Please provide values below to convert joule/hour [J/h] to kilojoule/second [kJ/s], or Convert kilojoule/second to joule/hour.
1 J/h = 2.77778e-07 kJ/s. To convert joule/hour to kilojoule/second, multiply the value by 2.77778e-07; to go the other way, divide by it (1 kJ/s = 3599997.12 J/h). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Joule/hour
A joule per hour (J/h) is a unit of power representing the amount of energy (in joules) transferred or converted per hour.
History/Origin
The joule per hour has been used as a measure of power in various scientific and engineering contexts, especially where energy transfer rates are expressed over longer periods. It is derived from the SI unit of energy, the joule, divided by time in hours.
Current Use
Joule per hour is occasionally used in fields like heating, energy consumption, and industrial processes to quantify power over extended durations, though it is less common than watts for standard power measurements.
Kilojoule/second
A kilojoule per second (kJ/s) is a unit of power equivalent to one kilojoule of energy transferred or converted per second.
History/Origin
The kilojoule per second is derived from the SI units of energy (joule) and time (second), and has been used in scientific and engineering contexts to measure power, especially in fields like physics and energy studies.
Current Use
It is used to quantify power in various applications, including electrical power, mechanical power, and energy transfer rates, particularly where kilojoules and seconds are the relevant units.
