dBm to watts

dBm or decibel-milliwatt is an electrical power unit in decibels (dB), referenced to 1 milliwatt (mW). One watt is the power equal to the rate of energy of one joule per second in an electrical circuit. One watt is also equal to the power produced in a circuit with a voltage potential of one volt with a current of one amp.

The watt is the SI derived unit for power in the metric system. Watts can be abbreviated as W; for example, 1 watt can be written as 1 W.

How to convert dBm to watts

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

P(W) = 1W ⋅ 10(P(dBm) / 10) / 1000 = 10((P(dBm)- 30) / 10)

Example

Convert 43dBm to watts:

P(W) = 1W ⋅ 10(43dBm/ 10) / 1000 = 19.9526W
