Convert decibel (amplitude)s to decibel (power)s
How to convert decibel (amplitude)s to decibel (power)s
Convert through a plain ratio: decibel (amplitude) → ratio → decibel (power). Logarithmic units cannot be converted by multiplying alone.
Decibel (amplitude): For voltage, pressure and other field quantities. 6 dB is roughly double the amplitude — and the same fourfold change in power.
Decibel (power): Ten times the base-10 log of a power ratio. 3 dB is roughly double the power.
