Convert watt to kilojoule/hour
Please provide values below to convert watt [W] to kilojoule/hour [kJ/h], or Convert kilojoule/hour to watt.
1 W = 3.59999999712 kJ/h. To convert watt to kilojoule/hour, multiply the value by 3.59999999712; to go the other way, divide by it (1 kJ/h = 0.277777778 W). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Watt
The watt (W) is the SI unit of power, defined as one joule per second, representing the rate of energy transfer or conversion.
History/Origin
The watt was named after James Watt, the Scottish engineer and inventor, in 1889. It was adopted as the SI unit of power to standardize measurements in science and engineering.
Current Use
The watt is widely used today to quantify power in electrical devices, engines, and energy consumption, serving as a fundamental unit in physics, engineering, and everyday applications.
Kilojoule/hour
A kilojoule per hour (kJ/h) is a unit of power representing the amount of energy in kilojoules transferred or converted per hour.
History/Origin
The kilojoule per hour has been used as a measure of power in contexts where energy transfer rates are expressed over time, particularly in engineering and scientific applications, though it is less common than standard SI units like watts.
Current Use
kJ/h is used in specific fields such as thermodynamics and energy management to quantify energy transfer rates, especially in systems where energy is measured in kilojoules and the rate is expressed per hour, though it is often converted to watts for standardization.
