Calculate level (dBu or dBV) to voltage (VRMS)

This calculator converts a given signal level in dBu or dBV to the appropriate voltage level for sinusoidal waveforms.
Just enter either a level in dBu or in dBV, depending on your reference level.

Calculator

This calculator will output the voltage level for the entered decibel level.

dBu
dBV

The calculated voltage level is
0.000 Volt

Reference Base Voltage Application Standard Level Voltage at Standard Level
0 dBu 0.775 V RMS Professional +4 dBu 1.228 V RMS
0 dBV 1.0 V RMS Consumer / Home -10 dBV 0.316 V RMS
Since dBu is referenced to a smaller value, the same voltage will always come out 2.2 dB higher when referenced to dBu than when referenced to dBV. For example, 6 V = 15.56 dBV, but 17.78 dBu.
Another example: your manual specifies you need a signal level of -24 dBu. You can calculate the corresponding voltage here.
