Kilowatt (kW) to Milliwatt (mW) Conversion

Kilowatt to Milliwatt conversion explained with exact factors, step-by-step examples, and situations where this conversion is commonly used.

Conversion Formula

Milliwatt = Kilowatt × 1.000000e+6

To convert Kilowatt (kW) to Milliwatt (mW), multiply the value by 1.000000e+6. This factor is obtained by comparing their exact meter definitions.

Worked Example

Convert 1 kW to mW.

  • Step 1: Write the formula: mW = kW × 1.000000e+6
  • Step 2: Substitute: 1 × 1.000000e+6
  • Step 3: Result: 1.000000e+6 mW
So, 1 kW = 1.000000e+6 mW.
