# Unit of gradient of rider position vs length of wire watch

1. Hi guys,

This may not be a physics question per se but I encountered it while doing a lab report on an experiment using a Force-on-a-conductor balance. Not sure if relevant but this is what it looks like.

I am asked to plot a graph of the rider position(cm) vs length of wire(cm).
What is the unit of my gradient?
Would my gradient by cm/cm? Or is it cm/cm = no units?

It's just a ratio with no units because they cancel mathematically.

i.e. anything divided by itself = 1
