Forgive my lack of knowledge on the subject, but there seem to be two terms being used, and I'm not sure if they are interchangeable.

Can the "coefficient of rolling resistance" be equated to rolling resistance? If not, in the case of that chart posted above, what is the variable that is not stated that would convert a coefficient to the actual value that contributes to efficiency loss in driving?

I ask because in the case of aerodynamic drag, there is the Cd (coefficient of drag) that has to be multiplied by the Cda, or effective frontal area to get actual drag. Is there a similar equation that relates to rolling resistance?
