I will be building my first coil tomorrow; I have asked a few questions here and watched a ton of video about coil building. Now the one thing they always talk about but don’t explain is you targeted ohm. From what I saw a lot like the coils at .4-1.0 ohm builds. They don’t tell you how you determine what ohm you want to build, that seems to be a predetermined value. Does your mod, tank, dual coil or single coil come into play. I also saw that they said beginners should start above 1.0 in there builds. Just wondering what factors go into what ohms you want you coil at.

In general the thinner the wire and the more wraps the higher the ohms. Also depends on material. Kanthal for higher ohms, Stainless Steel for lower ohms same size wire.
You can also use Tungsten or nickel but they should be used in Temperature control only

Dual coils in the RBA/RTA mean half the ohm of the single coil. 2 x .5 ohm coils = .25 ohm
I have checked this out and they want you to input your resistance
No you just put in the wire type, gauge, Coil inner diameter, leg lenght and the resistance that you are looking for. It will tell you the number of wraps to get there.
I would try:
2.5mm to 3.5mm ID and 6 or 7 wraps.
Try each wire size and ID but stay at 6 or 7 wraps.
Adjust the coil position higher or lower to optimize air flow and flavour.
"ohms" is not so important with a regulated device.
Coiling is the easy part, it's wicking that can be the bugbear.
Best of luck.

Each wire size (AWG) has a SET resistance per length of wire.
For example, I put in 3MM inner diameter, 26 AWG Kanthal A1, 2 MM leg length and desired ohm .5. It tells me I need 5 wraps if the legs are in same direction or 4 if they are in opposite direction.
Changing it to the same in SS says I need 8 or 7 Wraps

Yes, but steamengine has clapton wire as an option. You need to know the gauges used to input there
You have a regulated device. Forget about the ohms, for now. Think about coil mass, and surface area. Thicker wires have more surface area than an equivalent length of thinner wire, which means they have more contact with the wet wicks and will produce more vapor when they get hot. However, they also have more mass which means it will take more power to get them hot, take longer to get there, and stay hot for longer after you release the button (aka they will have longer "ramp up"/"ramp down" times). To reduce coil mass but keep the same or similar surface area, you can use a longer length of thinner wire. This will have a higher resistance than the shorter, thicker wire, but you're using a regulated device, so it doesn't really matter, since you can adjust the power level to whatever you want (within the device's limitations, obviously), regardless.
