How to convert ratios to decades
Convert through a plain ratio: ratio → ratio → decade. Logarithmic units cannot be converted by multiplying alone.
Ratio: The plain multiplier every logarithmic unit here converts through. Read a decibel figure as an encoding of this number.
Decade: A factor of ten. Bode plots are drawn per decade.
