dBm to mW

dBm or dBmW (decibel-milliwatts) is a unit of level used to indicate that a power level is expressed in decibels (dB) with reference to one milliwatt (mW). It is used in radio, microwave and fiber-optical communication networks as a convenient measure of absolute power because of its capability to express both very large and very small values in a short form compared to dBW, which is referenced to one watt (1000 mW).

A milliwatt (mW) is one thousandth of a watt (W), or there are 1000 milliwatts in a watt. The watt is an SI derived unit of power. One watt is one joule of energy per second.

How to convert dBm to mW

The power conversion of dBm to mW is given by the formula:

P(mW) = 1mW ⋅ 10(P(dBm)/ 10)

So

1dBm = 1.258925mW

Example

Convert 13dBm to milliwatts:

P(mW) = 1mW ⋅ 10(13dBm/ 10) = 19.95mW
