Kilowatts to milliwatts converter
Milliwatts (mW)
1 kilowatt = 1,000,000 milliwatts
How to convert kilowatts to milliwatts
mW = kW × 1000000
Multiply the number of kilowatts by 1000000 to get milliwatts. Going the other way, divide by 1000000 (or multiply by 0.000001).
One kilowatt is exactly defined as 1000000 milliwatts (to 12 significant figures), and one milliwatt is 0.000001 kilowatts.
Worked examples
- Convert 5 kilowatts: 5 × 1000000 = 5,000,000 5,000,000 milliwatts.
- Convert 12.5 kilowatts: 12.5 × 1000000 = 12,500,000 12,500,000 milliwatts.
- Convert 250 kilowatts: 250 × 1000000 = 250,000,000 250,000,000 milliwatts.
