How to Convert Microwatts to Watts

To convert a microwatt measurement to a watt measurement, multiply the power by the conversion ratio. One microwatt is equal to 1.0E-6 watts, so use this simple formula to convert:

watts = microwatts × 1.0E-6

The power in watts is equal to the microwatts multiplied by 1.0E-6.

For example, here's how to convert 5 microwatts to watts using the formula above.
5 µW = (5 × 1.0E-6) = 5.0E-6 W

Microwatts and watts are both units used to measure power. Keep reading to learn more about each unit of measure.


One microwatt is the power equal to 1/1,000,000 of a watt, or the energy consumption at a rate of 1/1,000,000 of a joule per second.

The microwatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "micro" is the prefix for 10-6. Microwatts can be abbreviated as µW, for example 1 microwatt can be written as 1 µW.


One watt is the power equal to the rate of energy of one joule per second in an electrical circuit. 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.
