dBm to Power Converter

Convert between dBm and Milliwatts (mW) with this converter.

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:

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