How to Convert Microwatt to Milliwatt

1 microwatt = 0.001 milliwatts

Milliwatt = Microwatt × 0.001

Example: 100 µW × 0.001 = 0.1 mW

Reverse Conversion

To convert milliwatts back to microwatts:

  • Remember, 1 milliwatt equals 1000 microwatts.
  • To convert 0.1 mW to µW, multiply 0.1 x 1000, resulting in 100 µW.
