How to Convert Milliwatt to Microwatt

1 milliwatt = 1000 microwatts

Microwatt = Milliwatt × 1000

Example: 500 mW × 1000 = 500000 µW

Reverse Conversion

To convert microwatts back to milliwatts:

  • Remember, 1 microwatt equals 0.001 milliwatts.
  • To convert 500000 µW to mW, multiply 500000 x 0.001, resulting in 500 mW.

500 mW is also equal to:

  • 12 watt
  • 0.0005 kilowatt
  • 0.00067024 horsepower (electric)
