The milliwatt conversion selector above 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.
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×m2/s3
