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.
