How to Convert Milliwatt to Megawatt
To convert from Milliwatt (mW) to Megawatt (MW), multiply the value by 1.000000e-9.
Formula: MW = mW × 1.000000e-9
Reverse: mW = MW × 1.000000e+9
Step-by-Step Example
- Start with your value in Milliwatt. For example: 5 mW
- Multiply by the conversion factor: 5 x 1.000000e-9
- The result is: 5.000000e-9 MW
