Technically a sub-ohm coil is a coil that reads below 1 ohm on your ohm meter. Does this answer your question?
If you don't have an ohm meter you MUST get one.
You cannot fire a coil that you have not measured.

You are not yet prepared to build sub-ohm coils. Research and self-educate yourself.
Explain it for the dumb noob: Ohm's Law calculations. <-- how to determine if a coil is safe for your batteries.
Inexpensive Mechanical Mod/RDA Setup <-- tools & supplies for coil building
Information Resources for Your First RBA <-- necessary core knowledge for coil building

It depends on the diameter of the coil. Your resistance (Ohms) will be proportional to the length of the wire. 13 wraps on a big coil will be a longer wire than 13 wraps on a small coil, so higher resistance. Go look at a resistance calculator like this: Steam Coil Calculator.
Please go back to the top of your thread, and follow the links people have provided for you. I don't think you "got it" yet.
Depends on what your ohm meter says.
Coil calculators should be considered an estimate still in need of verification using an ohm meter before use.

Coil Toy Calculator
That depends upon what you are going to wrap your wire around. Use the above calculator. Click on each of the following drop down menus for the wire gauge (WYG - 26), diameter of the screwdriver or drill bit you are wrapping the coil around, and target resistance (1.0 ohm). Then click on the "wraps" window under results.
- Lets see, using a 26 gauge wire wrapped around a 2 mm drill bit for a 1 ohm coil would require 11 wraps.
- Using a 28 gauge wire wrapped around a 2 mm drill bit for a 1 ohm coil requires 7 wraps or loops.
- A 30 gauge wire around a 2 mm drill bit for a 1 ohm coil will require 4 wraps.
You see, you are NOT ready yet and have a lot to learn. Do your homework. Get the proper tools and supplies (precision screwdriver set, tweezers, butane torch, and most important an ohm reader). Click on the links that I already provided to you. All the info you need is there.

The warnings and references are valid. The reason for sub ohm coils is response time. If the time from when you press the power button and the time you get vapor is good - don't bother with sub ohm coils. 
Save yourself a lot of grief by not attempting this until you have the knowledge, an ohm meter, a voltage meter and appropriate batteries. Building your own coils comes with the responsibility to protect yourself and others around you. Turn your eagerness towards learning and you will be much happier with your results.
Why o why do people ask for advice and then ignore the great resources that are provided?
If you cant figue out by yourself what your coil is going to be then you should not be building it! PERIOD!
If you need help understanding the folks are realy great about steering you right.
Keep reading Keep learning Keep safe keep vaping.

People are too lazy to read for themselves and want instant gratification. They want to be spoon fed and not do their homework. Makes you wonder how they got through high school.
"Just tell me exactly what I need to do. I don't need to know the why or how parts".
Its lazy people like this who will have mods and hands that look like this:

You were given help and informative links and warnings about the dangers, seems like you payed no attention due to your second question.
I doubt seriously anyone was trying to be rude, vaping safely is a major concern for anyone using a mechanical.
There is no way to use a mechanical safely without the basic equipment & battery safety knowledge.
If you were expecting an awh heck just wrap this and wing it type answer, we don't give those kind because they can be dangerous.

Maybe, perhaps a little - but only because people want you to be safe.
Let's review.
You asked a question.
It was answered by several forum members providing links to answer your question plus a lot of other excellent information.
Then you ask another question showing that you haven't looked at any of the links.
It's a friendly forum franco4, and I really hope you stick around - but particularly right now, battery, coil and mod safety is front and center for everyone in the vaping community.
So even if you do nothing else, please, do yourself a favor and read those links.

Susan is right about what a sub coil is, you have been given a lot of good advice already. The one thing that no one has mentioned yet, about ohm readers is they're not all good for coil building close to 1 ohm or lower. You need to get an ohm reader that reads to the third digit and NOT only to the second digit.
Example:
Good ohm reader
1.04 ohm
Bad ohm reader
1.0 ohm
The reason why this is bad any coil you make between 0.95-1.04 will show up as 1.0 ohms.
well 12 wraps around a 1.7 mm mandrel will get ya to about 1.2 ohms with 26. For build above 1 ohm, might want to use 28 gauge instead.
