Milliwatts to kilowatts converter
Kilowatts (kW)
1 milliwatt = 0.000001 kilowatts
How to convert milliwatts to kilowatts
kW = mW × 0.000001
Multiply the number of milliwatts by 0.000001 to get kilowatts. Going the other way, divide by 0.000001 (or multiply by 1000000).
One milliwatt is exactly defined as 0.000001 kilowatts (to 12 significant figures), and one kilowatt is 1000000 milliwatts.
Worked examples
- Convert 5 milliwatts: 5 × 0.000001 = 0.000005 0.000005 kilowatts.
- Convert 12.5 milliwatts: 12.5 × 0.000001 = 0.0000125 0.0000125 kilowatts.
- Convert 250 milliwatts: 250 × 0.000001 = 0.00025 0.00025 kilowatts.
