Convert joule/hour to kilowatt
Please provide values below to convert joule/hour [J/h] to kilowatt [kW], or Convert kilowatt to joule/hour.
1 J/h = 2.77778e-07 kW. To convert joule/hour to kilowatt, multiply the value by 2.77778e-07; to go the other way, divide by it (1 kW = 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.
Quick Reference
- 1 J/h = 2.77778e-07 kW
- 1 kW = 3599997.12 J/h
- 10 J/h = 2.77778e-06 kW
- 100 J/h = 2.77778e-05 kW
How to Convert Joule/hour to Kilowatt
1 J/h = 2.77778e-07 kW
Example: convert 15 J/h to kW:
15 J/h = 15 × 2.77778e-07 kW = 4.16667e-06 kW

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.
Kilowatt
A kilowatt (kW) is a unit of power equal to 1,000 watts, used to measure the rate of energy transfer or consumption.
History/Origin
The kilowatt was introduced as part of the metric system to provide a practical unit for measuring larger power outputs, especially in engineering and electrical contexts, and has been widely adopted since the 20th century.
Current Use
The kilowatt is commonly used today to specify the power output of engines, electrical appliances, and power generation facilities, as well as in billing for electricity consumption and capacity ratings.
Frequently Asked Questions
