I understana that Ohm's Law is V=IR, but how do I use this law to give an alternative set of units that could be used to designate the voltage? I've tried to search every where possible to figure this out, but everything I read loses me. Can some please explain this so it its easy to understand?

The law you mentioned says that the voltage is equal to the amperage times the resistence. V stands for voltage.
So what is the problem? You have everything you need.

Ohm's Law says "the current (I) in any circuit is directly proportional to the voltage (E) and inversley proportional to the resistance (R)". Mathematically, this says I =E/R or E=IR.
E (voltage) is measured in volts or milivolts or kilovolts, etc.
I (current) is measured in amperes or miliamps or kiloamps etc.
R (resistance) is measured in ohms or kilohms or megohms, etc.
Other than that I guess I do not understand your question.

Really difficult to understand what it is you want.
The problem is explaining what voltage is in the first place is very difficult, and does not have a "set of figures" as such.
Hence articles like this one....

to find voltage(v) you multiply(x) the amperage(i) by the resistance(r)* to find the resistance(r) you divide(/) the voltage(v) by the amperage(i) *and to find the amperage (i) you divide(/) the voltage(v) by the resistance(I) hope this gives you what you need to know

V=I*R
I=V/R
R=V/I
