Stages Slider and Potentiometer Values

I"m looking at the ‘Controls’ schematic for the Stages module. Does anyone know what the ‘B’ stand for in the 20kB value for sliders? I’m confident it means 20k Ohms but I have never seen 20kB before… to me, it represents kilobytes.

Thanks!

The B refers to the response curve (linear).
