Microwatt Converters

Convert microwatts to milliwatts, watts, nanowatts, picowatts, kilowatts and other power units.

What this tool does

Convert microwatts to milliwatts, watts, nanowatts, picowatts, kilowatts and other power units. Type an amount in microwatts, choose the units, and the tool converts it to milliwatts. It offers 9 power units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one from 9 options, including Microwatt, Nanowatt, Picowatt, Milliwatt, Watt, Kilowatt. Starts as Microwatt.
  • To: Choose one of the same 9 units as "From". Starts as Milliwatt.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from microwatts to milliwatts:

  • 1 µW = 0.001 mW
  • 5 µW = 0.005 mW
  • 10 µW = 0.01 mW
  • 50 µW = 0.05 mW
  • 100 µW = 0.1 mW

Multiply the number of microwatts by 0.001 to get milliwatts. Both units are exact definitions, so 0.001 is the exact factor: 1 µW = 0.001 mW.

Limitations

  • Converts units of power only. Decibel-milliwatts (dBm) are a logarithmic scale and are not included.
  • Does not convert to or from voltage or current.

FAQs

Q: How many watts is one microwatt?
A: One microwatt is 0.000001 watt (one millionth of a watt), or 0.001 milliwatt.
Q: How many nanowatts are in a microwatt?
A: One microwatt is 1,000 nanowatts.
Q: Does it convert to dBm?
A: No. dBm is a logarithmic scale and is not offered here.
