Say if I have 1ohm reading on a dual coil set up, is it really 1ohm or do I have to do any dividing?
Thanks,

Yes and no.
You would get the same reading if you would put in one single wire of the same length but double diameter if that makes sense.
Basically, given you have two wires, the meter/mod sees them as one.
It's always worth mentiong, just in case: be careful with double coil, the draw on the battery is high with that kind of resistance.

I am about to recoil a V9 I got from fasttech. I had two seperate wires(coils). The RDA has three posts. I would presume this then makes it one long coil.
I wanted to make sure before i start firing away on my k100 thinking i know my resistance.
I got the reading of my Vamo. I received it at 1ohm and will try replicate that.
So is it 1ohm?

If you're reading it from your mod, with both coils in position, it is 1ohm. Where you need to do math is measuring each individual coil before they're in the atty.
Why do i need to get the reading of each individual coil if the overall is right?
It helps if each is close to each other in resistance. I sometimes forget how many wraps I've put on a wick, so it's a good way to check before I build the whole thing.
Ok great, so do both coils have to be the same ohms?
I am wrapping them identical anyway but would there be an issue if they were?

In all actuality, it probably won't make a difference unless they're 1 or more ohms apart. It won't hurt the mod, just one may heat up quicker than the other which can effect the taste and/or vapor production.

The coils need to be as close as possible in resistance. Current flows through the path of least resistance, so if one coil was lower resistance, one will heat up faster while the other barely glows. Performance will suffer.
It is one positive post and 2 ground posts. So it is not really one long coil but 2 coils in parallel. To keep 1 ohm total resistance, you want to make two, 2 ohm coils.
Aren't dual coils common ground? I only have one dual and it's a knock-off it reads a common ground, but it might be due to improper construction. I haven't yet delved deeper into it as, so far it still works fine. I will attempt to deconstruct it once it dies just for the hell off it, and because I can.
if you want a good vape, make 2 separate coils around 0.5 ohm, and when you latch the 2 ends down on the third post it will be one big 1 ohm coil, but that way you know what each side is running...dont forget to heat it up and check for hot spots! 
Technically, they are common ground and common positive which makes them a parallel circuit. The separate positive posts simply make it easier to work on, and spread the heat to a larger area for more vapor production.

That would be series, the dual coil attys are set up for running in parallel, and you cannot run them in series using all 3 posts. To run in series, the first coil would start off at the center positive terminal, the end of the coil would attach to the beginning of the 2nd coil, and the 2nd coil would terminate at either negative post you want. Only 2 posts could be used.
If you had one coil going from the center post, to one of the negative posts, and then second coil started at that same negative post, and terminated at the 2nd neg post (which is what you'd have to do for series... but the atty is not built for that) then you would only have one coil powered, the other would do nothing as it would be attached to ground on both terminals, it would receive no power.
Even if there was an atty setup for running dual series coils, it would be completely pointless. There would be no reason to not just wrap one single 1ohm coil. And wrapping two .5ohm coils in parallel could be incredibly dangerous if the person didn't know what they were doing. That's over 15amps with a somewhat fresh battery.
