As I almost finish understanding the terms volts,watts,amps,and ohms...how do I use the online calculator and what is my objective exactly? Do I have to figure out how low my ohms can be? For example I put in a Panasonic 18650 imr battery that's has a maximum of 4.2 volts and has 2250mah and I put it in the calculator and I get 1.8 ohms. What does the 1.8 mean exactly? Does it mean I that's the lowest I can go without shorting out the battery?

maybe this will help..I'm not to sure as I am very new to vaping but Taste Your juice has been a great resource.

4.2 is the highest voltage your battery will be after a complete charge. Your goal in finding the ohms is to get the resistance of the atomizer you're using. To my knowledge, this cannot be done using a calculator. You'll need to use a multimeter to physically test the resistance of the device you're working with. Knowing the resistance enables you to make an informed decision as to the highest voltage/wattage setting you can go to without "popping" the coil or doing something else to damage the device. The following chart has some good information as to where you shouldn't be in terms of voltage/wattage (wattage is commonly referred to as power):
With respect to the chart above, you can start anywhere from the blues and make your way up, but you should be wary of entering the purples, and when going into the reds and maroons, you need to be as careful as possible so as to prevent any damage.
Edit: To help you better understand, mAh has absolutely nothing to do with much of anything other than telling you approximately how long your battery will last.

I don't quite understand your question. An ohms law calculator has nothing to do with what battery you are using. Do you mean a "C" rating calculator?
With an ohms law calculator you plug in any two of the factors (say ohms & volts) and it will tell you the other two factors of ohms law. (amps & watts)

For some reason watts weren't illustrated. Pretend there is a balloon at the end of the straw the monkey is blowing into. The size of the balloon would be the watts. The watts would also be the amount of water in the pool at the bottom of the waterfall.
What Exactly is your Objective? And what would you like Ohms Law to help you do?
what device are you using? ego? vamo? what?
skip the charts and calculators with a variable volt device, and make it easy on your self.
use the +2V rule
You have a clearomizer, it has a 2 ohm head. so 2 ohms +2 = 4 - so set the device to around 4 volts (3.7 to 4.2) start a little lower then 4 and go up - adjust for taste.
works every time, for any resistance.

The +2 rule seems to nudge at the higher end of the chart. I normally set my vv devices at 3.8 - 4.2. That being said, should I be getting the 1.8 or 2.4 heads? Originally, I was leaning towards the 2.4, but now I'm second guessing myself.
If you want to (or can (maybe an Ego? ) ) vape at 4.4v then go for a 2.4 head.
Personally for me the best alround resistance for my unregulated Ego`s and the Vamo is around 2.0ohm but I always rewire my devices first and check resistance.
An unregulated ego will start at 4.2v and run down (much the same as a mech mod) the Vamo of course is adjustable but I like to give batteries an easy life
As a rule of thumb any resistance plus two volts will give you 8 watts. For some juices and devices that is the upper limit before tasteing burnt but it works fine for my tobacco flavours (and other strong juices) but might be worth dropping a few points of voltage for softer "Fruit" or "desert" flavours.
Edit: having said that I have an Evod I`ve wired to 1.7ohm and it tastes great on a fresh charged Ego at 4.2v which "theoretically" puts it in the burn zone! But being a bottom feeder it runs in juice and lessens the risk of dry hits.
Depends on wicking as well it seems

have a mix of vv and non vv ego batteries - usually use the vvs (I have an itaste 3.0 and an ego twist), but was going to get some standard egos to use for backups.

with a regular old ego i would get 1.8 ohms so they work for a longer time before the vapor drops off.
its not a hard rule it always gives you the general starting area. even like your saying - 1.8 and 2.4, is right around 4 v
and the idea behind VV is so you dont have to worry should i get 1.8 or 2.4. you can always change the voltage to fit whats needed. personally i like the 1.8 to 2 ohm range. but if need be i will use whatever is available and just turn up the voltage

Okay, thank you! I have a package of 2.4 heads - I'll save those to use exclusively with the vvs.
The higher the resistance, the lesser the amps (current) and watts (power) using the same voltage. So, a fixed voltage ego is going to last longer with a higher resistance coil. In reading through, some of the threads, this seemed to get a little confusing. If you want longer battery life, use a higher resistance coil, which uses less power. So, a higher resistance uses less amps to achieve the same power. Less amps means longer battery life as battery life is measured in mAh (milliamp hours). Here is a good primer on Ohm's law and vaping:

Here is a good calculator:
Watts - volts - amps - ohms conversion calculator
Using these two tools, you can understand and easily calculate each of these variables and a few exercises will clear up the issue for you. It's not so important to understand the precise technical meanings of each of these terms, but, rather, to understand their relationship with each other.

I just found out that the EVODs I got from myvaporstore are 2.4. I like the results I get from them, so I'm retracting my previous comment. ;-) Glad I hadn't ordered anything else yet!
