#### Watts to Milliwatts

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.

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.

#### How to convert watts to milliwatts

One watt is equal to 1000 milliwatts:

1W = 1000mW

Watts to milliwatts conversion formula

The power in milliwatts P_{(mW)} is equal to 1000 times the power in watts P_{(W)}:

P_{(mW)} = 1000 ⋅ P_{(W)}

#### Example

Convert 5W to milliwatts:

P_{(mW)} = 1000 ⋅ 5W = 5000mW
