dBm to Watts Calculator
What is dBm to Watts Converter?
A dBm to Watts converter is a very useful tool in converting any power measurement that exists in dBm, or decibel-milliwatts, to watts. This conversion is very familiar in the fields of telecommunications, electronics, and audio engineering since it allows a precise measurement of signal strength and power output. In simple words, dBm is a logarithmic quantity that means power relative to 1 milliwatt, whereas watts is the unit that measures energy per unit time.
you can also calculate watts from dBm using the dBm to watts formula given below: P(W)Â = 1W â‹… 10(P(dBm)Â / 10)Â / 1000 = 10((P(dBm)– 30) / 10)
dBm to Watts Conversion
Formula: Convert dBm to Watts
To convert a power level from dBm to watts:
\[ P_{\text{W}} = 10^{\left(\frac{P_{\text{dBm}} - 30}{10}\right)} \]
Where:
- \(P_{\text{W}}\) = Power in watts
- \(P_{\text{dBm}}\) = Power in dBm
Example Calculation
If the power is 20 dBm:
\[ P_{\text{W}} = 10^{\left(\frac{20 - 30}{10}\right)} = 0.1 \text{ watts} \]
