Welcome to our professional dBm to Watts Converter. This tool is designed for RF engineers and technicians who need to translate logarithmic power levels into linear measurements like Watts (W) and milliwatts (mW) with extreme precision.
The Core Formula
To calculate the power in Watts from a dBm value, we use the following standard logarithmic-to-linear conversion formula:
$$ P_{(W)} = 10^{\frac{dBm - 30}{10}} $$
Or, if you need the result in milliwatts (mW):
$$ P_{(mW)} = 10^{\frac{dBm}{10}} $$
