Conversion Calculators

Voltage to dB Converter

This calculator converts the linear relationship between two voltages or powers into decibels, and decibels in power or voltage gain or attenuation.

Decibels are defined as ten times the log of a power ratio or twenty times the log of Voltage Ratio.

dB = 20log10(V1/V2) = 10log10(P1/P2)
