It's the distance that the pigment moved in relation to the distance that the solvent moved.

Basically, it's use is to make measurements easier to compare. For instance, if someone used a chromatography strip that was longer than someone else's, their distance traveled would be different, but the Rf value would be the same. Hope this helps. Slight Smile
