Does anyone have a resource for calculating mesh resistances? Thanks!

- calculations coil mesh
Hi. I don't have meshes yet, I want to do the calculations first. So like this... 316L, target resistance 1.5ohm, what spec mesh and measurements would I need? Thanks.
Small. And thin screen. So thin you might not be able to buy any, so it may not matter. You may have to buy stamped coils in the resistance you want. The other option is buying a sheet of 316 fine mesh screen (they make it. Generally for grease traps, so thinner may be hard to get.) and cutting off pieces. I would do a strip about 1 cm by 1/3rd of that, and get around half an ohm with screen made of 24 gauge wire.
Here's an image that may help or confuse you..
With this SS mesh wire, a 1.5 ohm coil would use approx 19 inches of material.
Are you using a non-regulated (AKA=MECH) device?
Why are the resistance/material of the coil important?
Cheers

Mesh wire strikes me as a contradiction in terms, but the question is a good one
Thanks everyone for the replies!
If I had my min post count this would go under atomizer hardware.
Let me explain what I am trying to achieve. Maybe best if I explain what I'm really after. I don't want to spawn a debate here but in my decade+ of vaping I am blown away by the flavor delivered by good disposables. Granted the throat hit and warmth are near non-existent and that in my opinion the nicotine delivery is actually a tiny fraction that of sub-ohms etc. My experimentation suggests that there is nothing special about the juice used in disposables, perhaps more sweeteners and flavor base but some bottled liquids have this. It seems that the difference is that the disposables use high resistance meshes. My first measurement looks like a ridiculous 4-6ohm but this could be my meter not being good enough I'll have to test further.
So whether or not you agree with me on the flavor claim I do want to try and replicate this in an RTA. From the comments and more research I see that this wouldn't be practical to build from mesh sheets and I don't know if you can buy the stamped ones like attached. So I think the best I could do is with coils instead; I think with 30AWG I could be made fit, though dual I think 1ohm ballpark would be the highest?
Thanks again!

It’s not that they do an awful job, it’s that they’re incredibly expensive if that’s all you use, and there’s no opportunity to quit in any way that’s easier than cigarettes. Numerous governments have done “anti-disposable legislation” that actually goes after the completion of the cigarette companies more than anything else. Worse, it effectively forces people now addicted to nicotine, one of the most addictive drugs that exists, to smoke cGarett’s. It’s frequently all kinds of asinine.
There kinda isn’t one. At least that I know of. Im not sure it’s even theoretically possible. Mesh isn’t a single wire. It’s more “cut a piece of screen, test it to see what the resistance is, and either use it or don’t”. Makes it really hard on mech users who don’t want to buy premade coils, but there you go. If you use a regulated mod, you just set the voltage to whatever voltage makes however many volts of draw you like (for me it’s -3.0) and go. I found with the stuff I was using they were generally near .5ohm ymmv of course.
Disposables have their points. THEYRE SO UNBELIEVABLY EXPENSIVE over time though. $600/mo vs. $30/mo
