What is the dBm to Milliwatts Converter?
The decibel-milliwatts (dBm) to Milliwatts (mW) converter is a specialized RF engineering tool. It reverses the logarithmic scale of electromagnetic signal strength back into linear, fractional electrical power.
How It Works (Algorithm)
To unravel a decibel logarithm, the calculator must use an exponential equation. It takes the inputted dBm value, divides it by 10, and raises the base-10 to that exponent. The resulting number is the exact linear power in milliwatts.
$$ P_{(mW)} = 10^{\left(\frac{P_{(dBm)}}{10}\right)} $$
The exponential function required to decode RF signal strength.
How to Use It
Enter the signal strength in dBm (e.g., 20 dBm). The calculator runs the exponential math and instantly outputs the linear power in milliwatts (mW). In this case, exactly 100 mW.
