I assume you are referring to Retention Factor and have been doing some chromatography. There's a few things that could take the initials RF so if you mean something else, just ask again with more specifics.
That said, there are no units to retention factor. It's a ratio. Pure ratios should never have units.
We can see this with a little mathematical proof.
rf value is calculated by dividing the distance your solvent travelled to the distance your compound travelled (always this way round. You should always get an answer between 0 and 1. if you don't, you've done it wrong).
So it's like saying cm/cm, which we can see works out unitless.

What is the full name of Rf value?
Retention Factor Rf == Distance traveled / total distance
What is rf value of eugenol?
The Rf value depends on the type of plate used and solvents.
How does saturation effect RF value?
Saturation affects the RF value in a significant manner. With saturation of the air, this will result into high RF value which cause poor resolution.Ê
What is the maximum and RF value can be?
1, if it completely solube in the solvent, it will travel with it, right to the solvent front.
A compound has a very high Rf value in a polar solvent what can you say about its molecular structure?
Rf Value - It tells you the affinity that the compound has to the solvent...High Rf = little or no polar groups and low Rf = more polar groups. Question: In TLC (thin-layer chromatography) when the compound has a high Rf the solvent is: a. less polar b. Is more polar Answer: a. less polar
What is the unit of rf?

What do you mean rf cable?
RF = Radio Frequency
Find the risk-free rate given that the expected rate of return on asset j is 14 percent the expected return on the market portfolio is 12 percent and the beta b for asset j is 1.5?
CAPM equation E(Rj) = rf + b[E(Rm) - rf] 0.14 = rf + 1.5(0.12-rf) 0.14 = rf + 0.18 - 1.5rf -0.04 = rf - 1.5rf -0.04 = (1-1.5)rf -0.04 = -0.5rf rf = 0.08 rf = 8%
