How to convert decibel (power)s to decades
Convert through a plain ratio: decibel (power) → ratio → decade. 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.
Decade: A factor of ten. Bode plots are drawn per decade.
