decibel (dB) conversion to voltage and power
Enter the value that you know in the appropriate box and hit [calculate] below that box
The dBm is a logarithmic measure of power compared to 1 mW,
which means that it is power dependent.|
It can be converted to a voltage, if the load impedance is known.
Typically the load impedance used in audio applications is 600 ohms.
|A simple rule to remember:-
When working with power, 3 dB is twice the power, 10 dB is 10 times.
When working with voltage or current, 6 dB is twice, 20 dB is 10 times
