Our tool converts dBm values to watts instantly for your convenience.
How to Use the dBm to Watts Calculator
This calculator converts dBm to Watts and takes into account the impedance of the medium through which the signal is traveling.
Instructions:
- Enter the dBm value that you wish to convert in the first input field.
- Enter the impedance (in Ohms) in the second input field.
- Click the “Calculate” button to perform the conversion.
- The results will be displayed in a table below the input fields. The first row shows the power in Watts, and the second row shows the power in Watts considering the given impedance.
Explanation of Calculation:
The formula to convert dBm to Watts is given by:
Power (W) = 10^(dBm / 10) / 1000
The power to impedance calculation is done by:
Power to Impedance = sqrt(Power (W) * Impedance (Ohms))
Limitations:
- This calculator assumes that the impedance value is greater than zero.
- Ensure that all the fields contain valid numbers before pressing the “Calculate” button. The script will alert you if any invalid or empty fields are encountered.
- This calculator is intended for general informational purposes only and may not be suitable for precise engineering calculations. Always double-check your calculations using professional tools for critical applications.
