Convert Milliwatts to Kilowatts
Convert Milliwatts (mW) to Kilowatts (kW) instantly and accurately.
Conversion Formula
kW = mW × 1.000000000e-6
About Milliwatts
A milliwatt (mW) is 10⁻³ W - the power scale of consumer wireless communications. Wi-Fi access points transmit at 100 mW (20 dBm); mobile phones peak at up to 1,000 mW. A laser pointer emits 1-5 mW; an LED indicator 10 mW; Bluetooth Classic peaks at 100 mW. Standby power implications: 1 mW × 10⁹ devices × 1 year = 8,760 MWh - enough to power a small town, underscoring why milliwatt standby matters at scale. 1 mW = 10⁻³ W.
About Kilowatts
A kilowatt (kW) is 1,000 W - the everyday unit for home, vehicle, and industrial power. Average US home consumption is ~1.2 kW continuous (~10,500 kWh/year). EV motors range from 30 kW (city cars) to 600+ kW (performance models); a Tesla Model S Performance produces 560 kW (751 hp). Industrial gas turbines on commercial aircraft generate 20,000-100,000 kW. Solar installations are sized in kW-peak. Industrial electric motors span from fractional kW to thousands of kW. 1 kW = 1,000 W = 1.341 hp = 3,412.1 BTU/h.
