Hi friends, so I just got my replacement coils in for the uwell Whirl and I ordered one of each kind they had at element vape. A 1.8 ohm and 0.6 ohm. They were cheap enough and I didn’t know what to get so I just got both. Now they’re here and I haven’t the first clue which ones I should use or what the difference is between them. I know 0.6 is sub ohm (well I think I know that) so for MTL should I use the other ones? Confusion abounds. Can you guys help me and use lots of laymen’s terms so I can understand this once and for all?
1.8 vs 0.6-What’s the difference?

The higher ohm(resistance) is considered mtl. and resistance over 1.0 is thought to be mtl. The lower the number of ohms( 0.6) is the sub-ohm resistance. the higher number you have a hard resistance to getting a hit and more of a drag on getting the vapor into your mouth. The lower 0.6 ohm has less resistance and it had less of a drag so its easier to get vapor into your mouth. Also you need a higher watt with the lower resistance than with the higher one. Just experiment with them and see which you prefer. Neither is right or wrong just a bit different in performance and style of vaping.

Look at the colored strip on the top of the box. Green is NiChrome 0.60 Ohm coils meant to be used at 18 Watts to 22 Watts. Red is 1.80 Ohm NiChrome coils meant to be used at 10 Watts to 15 Watts. So they are both MTL coils using the same wire. Decide what Wattage range you want to vape in and use the appropriate coil.
Aside from the wattage they require to heat, there are other differences in drop-in coils of the same type with different resistance. The coil size or arrangement can be different, and since most factory coils draw air through the middle with wicking wrapped around the actual coil of wire this changes the airflow or draw and sometimes how warm it is, because with less or more air the vape is warmer or cooler. Flavor can be different as well.
The .6 coil is sub-ohm, but that does not mean it has to be or was intended to be used at high wattage for big clouds.

@jtbje the coils you had already in use likely have the resistance marked on them somewhere. Possibly not. In the end, try out both coils but be prepared to like one style more than the other, and play around with them at different wattage and airflow settings. Which one you like more is all about personal experience.
0.6= more cloud, hotter vape, more juice used, shorter time before battery’s need recharged.
1.8= less cloud, cooler vape, less juice used, longer battery time.
This is considering they are both used at the same wattage and with the same type of drag on the tank.
YMMV

i use high resistance coils for mtl, but lately, i've been enjoying .6 coils for a cool, restricted dtl vape.
no big clouds but tons of flavor.

So… your Blow Dryer Dies.
No Big deal. You just hop in the car and drive to Blow Dryers R Us to get a New One. But when you get to Blow Dryers R Us, you find that they just got done doing a Year End Blow Out Sale (YEBOS). So there is only 2 Blow dryers left.
One is a Smallish model. Almost something you would see in a Oshkosh B'gosh store. And the other a Ginormous Monstrosity that looks like it could double as a Leaf Blow. But, as a Savvy Shopper, you know that Size can be deceiving.
Which one puts out More Heat?
So you check out the Box on the Smaller One and under a WARNING to Never use while Scuba Diving, it says that it puts out 750 Watts. And the Bigger One ( which actually Does say it can be used as a Leaf Blower for Bonsai Trees) it says it puts out 3,000 Watts.
Sooooo…. What Exactly is a Watt? And does More Watts mean More Heat?
Luckily, a Blow Dryers R Us employee comes by and explains that Watts are a Measure of Power. And that More Watts means More Power. So, yeah, the Bigger Blow Dryer will put out More “Heat”.
(WARNING: Slight Math to Follow)
For us and e-Cigarettes, Watts are Mostly how we Describe the way we Vape. I’m sure that you have heard people say I use Bla Bla Bla Tank at 25 Watts. Or my Bla Bla Bla RTA tastes best at 50 Watts.
Watts are a Calculated Value. And the way they are Calculated for a given Coil is you take the Voltage that your Mod is Outputting and then Square it. Then take that Amount and Divide it by the Resistance (in Ohms) of the Coil.
Ie: Wattage Formula => (Voltage x Voltage) / Ohms = Watts
EXM: Say your Mod puts out 4.0 Volts. And you put and Atomizer on it with a 1.8 Ohm Coil. => (4.0 x 4.0) / 1.8 = 8.9 Watts. So with a 1.8 Ohm Coil on a Mod that is Outputting 4.0 Volts, you are Vaping at 8.9 Watts.
EXM: Now you put a 0.6 Ohm Coil on that same Mod which is Outputting 4.0 Volts. => (4.0 x 4.0)/0.6 = 26.6 Watts
So with a 0.6 Ohm Coil on a Mod that is Outputting 4.0 Volts, you are Vaping at 26.6 Watts.
As you can see, the 0.6 Ohm Coil is producing Much More Wattage than the 1.8 Ohm Coil with the same Voltage. So just like Blow Dryers, the 0.6 Ohm Coil will be Hotter Hit at the same 4.0 Volts.
All this is Key for Mods where you Can Not adjust the Output Voltage. Because on Mods where you Can’t Adjust the Voltage, like the Whirl, you Adjust the Hit you get be using High Ohm Coils for a Cooler Vape. And Lower Ohm Coils for a Hotter Vape.
Way, Way TL/DR:
For the Same Voltage, a Lower Ohm Coil will give you a More Vapor and a Warmer Hit. And a Higher Ohm Coil will give you Less Vapor and a Cooler Hit
Way, Way, Way TL/DR:
You should Really try Both on your Whirl and see which one you like Best. And Never shop at Blow Dryers R Us after they have a YEBOS.

It’s this kind of help that really makes this forum so valuable. Zoid, thank you for explaining that so well. I’ve been so confused and this I can follow. You should teach a class.
I will try both and see which one I like. Many thanks from Texas!
I didn’t even see the watts on the box LOL thank you for pointing that out!

You guys are amazing and awesome and I don’t know how anyone navigated vaping without this forum. I wish people were this friendly in real life.
Funny you should Mention that.
Because I spent about 1/3 of my working career Standing in front of a Whiteboard explaining Math Concepts to students.
LOL
@jtbje Ah yes, the great rabbit hole continues to go down. To add to the mix, as I mix my own juice, those 2 will put off a different taste to the same juice. In a complex vape, the .6 will help all flavors shine in the juice where the 1.8 will only pick up main flavors due to wattage. It is a slippery slope but I would do as above mentioned and try them both to find out which one you like better. The .6 ohm would be a good one for use with more airflow like you Sub Tank Mini fully open and the 1.6 ohm with the smallest hole only. Follow the directed wattage on package of course. Hope this helps!

Oh, also the difference between the 2 are how efficiently it atomizes the nic in the juice. I use 1.8 but 1.6 is close enough. The higher the ohm, the more nic is needed. For instance, personal experience, with a 1.8 ohm coil I would use 24 mg and vape 4 ml of that in a day which equals 96 mg per day even though that is not what is ingested but for simple math. Using a sub ohm coil, mine was .7 ohms, I would vape 15 ml of 6 mg a day. Easy math puts it at 90 mg. Notice that total mg used is roughly the same as it would be harder to vape 15 ml per day on a 1.6 ohm.
I don't know about this particular brand but often the .6 coil will have a larger hole for air flow while the 1.8 will be more narrow for a tighter draw. That may or may not be the case with these.
The .6 ohm likely has thicker wire which will require more wattage to ramp up in the same amount of time as the 1.8 ohm coils. However the .6 ohm coils will likely lead to more vapor.
Normally, the higher ohm coils will lead to longer battery life (because of lower wattage) and use less liquid because of less vapor.

Grimwald, I believe that you made an error.
0.6 is less than 1.8, so 0.6 would use thinner wire or less wraps to make the coil. So as there's less resistance, it requires more power.
And even I'm learning from this thread, it's been very informative.

The thicker the wire, the lower the resistance
The bigger the coil (more wraps, bigger diameter), the higher the resistance
The power required depends upon the mass of coil
greek mule, we're on the same page.
I'll stick with .5 ohm coils or higher, to conserve power.
I'm using Vaporesso GT Coils and there are some good ones, GT Mesh .15 ohm and CCell2 .3 ohm. But they will deplete my batteries quicker.
