Convert decibel (power)s to ratios
How to convert decibel (power)s to ratios
Convert through a plain ratio: decibel (power) → ratio → ratio. Logarithmic units cannot be converted by multiplying alone.
Decibel (power): Ten times the base-10 log of a power ratio. 3 dB is roughly double the power.
Ratio: The plain multiplier every logarithmic unit here converts through. Read a decibel figure as an encoding of this number.
