Milliwatts to Watts Conversion
Enter the power in milliwatts below to get the value converted to watts.
How to Convert Milliwatts to Watts
To convert a milliwatt measurement to a watt measurement, divide the power by the conversion ratio.
Since one watt is equal to 1,000 milliwatts, you can use this simple formula to convert:
The power in watts is equal to the milliwatts divided by 1,000.
Milliwatts and watts are both units used to measure power. Keep reading to learn more about each unit of measure.
Milliwatts
One milliwatt is the power equal to 1/1,000 of a watt, or the energy consumption at a rate of 1/1,000 of a joule per second.
The milliwatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "milli" is the prefix for 10-3. Milliwatts can be abbreviated as mW; for example, 1 milliwatt can be written as 1 mW.
Watts
One watt is the power equal to the rate of energy of one joule per second in an electrical circuit.[1] One watt is also equal to the power produced in a circuit with a voltage potential of one volt with a current of one amp.
The watt is the SI derived unit for power in the metric system. Watts can be abbreviated as W; for example, 1 watt can be written as 1 W.
Watt's Law states the relationship between power, current, and voltage. Using Watt's Law, it's possible to express the power in watts as an expression using current and voltage.
PW = IA × VV
The power in watts is equal to the current in amperes times the potential difference in volts.
Combining this with Ohm's Law, it's also possible to express the power in watts using resistance in addition to volts and amps.
