1 µW = -30 dBmone microwatt in decibel-milliwatts
Decibel-milliwatt (dBm): Power level relative to one milliwatt: 10 times the base-10 logarithm of the power in milliwatts. 0 dBm is 1 mW and 30 dBm is 1 W.
Microwatt (µW): One millionth of a watt.

How to convert decibel-milliwatts to microwatts
To convert decibel-milliwatts to microwatts, divide the level by 10, raise 10 to that power, then multiply by 1000.
Formula
µW = 1000 × 10^(dBm ÷ 10)
Examples
- 0 dBm = 1000 × 10^(0 ÷ 10) = 1000 µW
- 20 dBm = 1000 × 10^(20 ÷ 10) = 100000 µW
- 30 dBm = 1000 × 10^(30 ÷ 10) = 1000000 µW

Frequently asked questions
- What is 0 dBm in µW?
- 0 dBm is 1000 µW. To convert decibel-milliwatts to microwatts, divide the level by 10, raise 10 to that power, then multiply by 1000.
- How do I convert microwatts to decibel-milliwatts?
- To convert microwatts to decibel-milliwatts, divide the amount by 1000, take the base-10 logarithm, then multiply by 10. The formula is dBm = 10 × log₁₀(µW ÷ 1000).
- Is this conversion exact?
- Yes. Both units have exact definitions and the factor 1000 is exact. Displayed results are only rounded when they have many decimal places.
