How to Convert Milliwatt to Kilowatt

1 milliwatt = 1 × 10-6 kilowatts

Kilowatt = Milliwatt × 1 × 10-6

Example: 2 12 mW × 1 × 10-6 = 2.5 × 10-6 kW

Reverse Conversion

To convert kilowatts back to milliwatts:

  • Remember, 1 kilowatt equals 1000000 milliwatts.
  • To convert 2.5 × 10-6 kW to mW, multiply 2.5 × 10-6 x 1000000, resulting in 12 mW.

12 mW is also equal to:

  • 0.0025 watt
