# Milliwatt conversions

The milliwatt conversion selector on this page selects the power measurement unit to convert to starting from milliwatts (mW). To make a conversion starting from a unit of power other than milliwatt, simply click on the "Reset" button.

## About milliwatt

The **milliwatt** is a unit of power equal to 0.001 watts (1 mW = 0.001 W), the derived unit of power in the International System of Units (SI).

The milliwatt (mW) is also equal to 1,000,000 nanowatts (nW), or 1,000 microwatts (μW), or 10^{-6} kilowatts (kW), or 10^{-9} megawatts (MW), or 10^{-12} gigawatts (GW) or 10^{-15} terawatts (TW).

1 mW = 0.001 W = 0.001 J/s = 0.001 N×m/s = 0.001 kg×m^{2}/s^{3}

Symbol: mW

Plural: milliwatts
