Convert power values from Decibel-milliwatts (dBm) to Watts (W) using our dedicated calculator.
Input the power figure in dBm and click the 'Convert' button:
Enter the power in dBm and press the Convert button:
The power conversion of dBm to watts is given by the formula:
P(W) = 1W ⋅ 10(P(dBm) / 10) / 1000 = 10((P(dBm)- 30) / 10)
Convert 43dBm to watts:
P(W) = 1W ⋅ 10(43dBm/ 10) / 1000 = 19.9526W
