Convert milliwatt to kilojoule/hour
Please provide values below to convert milliwatt [mW] to kilojoule/hour [kJ/h], or Convert kilojoule/hour to milliwatt.
1 mW = 0.00359999999712 kJ/h. To convert milliwatt to kilojoule/hour, multiply the value by 0.00359999999712; to go the other way, divide by it (1 kJ/h = 277.777778 mW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Milliwatt
A milliwatt (mW) is a unit of power equal to one thousandth of a watt, used to measure small amounts of power.
History/Origin
The milliwatt was introduced as part of the metric system to provide a convenient unit for measuring low power levels, especially in electronics and telecommunications, with its usage expanding alongside the adoption of the watt as the standard power unit.
Current Use
Milliwatts are commonly used today in electronics, audio equipment, and wireless communication devices to specify power levels, such as in battery-powered devices, LED brightness, and signal transmission power.
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.
Frequently Asked Questions
