I am not trying to pick on your wording but I would like to start off by saying that just because your mod can top out at 100 watts does not mean you must use all of them (unless in temperature control mode)
I would suggest this online tool:
Coil wrapping | Steam Engine | free vaping calculators
On the left side set the type of wire, kanthal is the default but many options here.
Set the gage of your wire to 26 if that is what you have available.
Select single, dual coil, etc in the Setup
Select the target resistance you want ( sorry I can't tell you the one you like)
Set the inner coil diameter based on what you using to wrap the wire around while building it.
It will tell you how many wraps you need for the coil you have told it you want to build.
Optionally watch this video here (or search for other build videos) where he is using 26 gage wire to do 4 wraps resulting on a .3 ohm build:
Good luck and happy vaping!
