Convert a decibel level into voltage and power ratios.
Decibels are logarithmic, so a negative boost means a fractional ratio, and the power ratio doubles the exponent of the voltage ratio. Every gain knob works in decibels but circuits respond to linear ratios, so converting between them is constant studio math.
Decibel to Ratio
Voltage ratio = 10^(dB/20); power ratio = 10^(dB/10)
Voltage ratio = 10^(dB/20); power ratio = 10^(dB/10) Decibels are logarithmic, so a negative boost means a fractional ratio, and the power ratio doubles the exponent of the voltage ratio.

This calculator takes 1 input: Decibel value. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
