Convert milliwatt to joule/hour
Please provide values below to convert milliwatt [mW] to joule/hour [J/h], or Convert joule/hour to milliwatt.
1 mW = 3.59999712 J/h. To convert milliwatt to joule/hour, multiply the value by 3.59999712; to go the other way, divide by it (1 J/h = 0.277778 mW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mW = 3.59999712 J/h
- 1 J/h = 0.277778 mW
- 10 mW = 35.9999712 J/h

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.
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.
