milliwatti
Milliwatt is an SI derived unit of power equal to one thousandth of a watt. It is written with the symbol mW, where the prefix milli- denotes 10^-3. Therefore, 1 mW equals 0.001 W, and 1 W equals 1000 mW. The milliwatt is used to express small power levels in electronics, optoelectronics, and other low-power applications.
In practical terms, milliwatts describe the power consumption or output of devices such as LEDs, sensors, and
Power is related to energy by time; energy is measured in watt-hours or joules, while a milliwatt-hour
Caution: The lowercase m distinguishes milli- from the megawatt symbol MW, which denotes 10^6 W. In English,
