Amplitude ratio to dB conversion:
For amplitude of waves like voltage, current and sound pressure level:
GdB = 20 log10(A2 / A1)
A2 is the amplitude level.
A1 is the referenced amplitude level.
GdB is the amplitude ratio or gain in dB.
dB to amplitude ratio conversion:
A2 = A1 · 10(GdB / 20)
A2 is the amplitude level.
A1 is the referenced amplitude level.
GdB is the amplitude ratio or gain in dB.

What is amplitude ratio?
A measure of the strength of a wave is its amplitude which is the vertical distance between the heights of the wave's peaks and the heights of its troughs. An ocean wave might be said to be 20 metres high, for instance, meaning that an observer can see that the bottom of the wave is 20 metres below the top of the wave. The amplitude of that wave would be 20 metres. If you wanted to compare two waves you could use their amplitude ratio, simply the ratio of their two amplitudes.
How do you use a number line to determine the ratio?
You do not use a number line to find a ratio
