Milliwatt (mW) to Petawatt (PW) Conversion

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

Conversion Formula

Petawatt = Milliwatt × 1.000000e-18

To convert Milliwatt (mW) to Petawatt (PW), multiply the value by 1.000000e-18. This factor is obtained by comparing their exact meter definitions.

Worked Example

Convert 1 mW to PW.

  • Step 1: Write the formula: PW = mW × 1.000000e-18
  • Step 2: Substitute: 1 × 1.000000e-18
  • Step 3: Result: 1.000000e-18 PW
So, 1 mW = 1.000000e-18 PW.
