Use a wheel radius in METERS (you'll have to calculate that yourself). Unfortunately, the wheel radius changes with speed and load, so an average is the best I can do. Ratios are unitless by definition.

Attached a screenshot of the plot for those who are without excel.

Wow that used up exactly the time I had left until I leave work hahahaha.
Thanks so awesome :thumb up:
