How to convert dBm to mW

The power conversion from dBm to mW or Watt is given by the formula:

P(dBm) = 10(P(mW)/10)

Example 1:

Convert 20 dBm to milliwatts:

P(mW) = 10(20/10) = 100 mW

So, the power of 20 dBm is equal to 100 mW or 0.1 W (Watt).

Example 2:

Convert -30 dBm to milliwatts:

P(mW) = 10(-30/10) = 0.001 mW

So, the power of -30 dBm is equal to 0.001 mW or 0.000001 W = 1 μW.
