dBm to Power Converter

Electronics Measurement

The \(\text{dBm}\) is an absolute unit of power, where the reference power (\(P_{ref}\)) is always 1 milliwatt (\(\text{1 mW}\)). It is the standard unit for expressing transmitter output power and receiver sensitivity in both \(\text{RF}\) and optical power systems.

$$P (\text{dBm}) = 10 \cdot \log_{10} \left( \frac{P (\text{mW})}{1 \text{ mW}} \right)$$

Conversion: You can convert directly between \(\text{dBm}\) and Watts:

$$\text{Power} (\text{mW}) = 10^{\frac{P (\text{dBm})}{10}}$$
