It depends on the gauge (thickness) of the wire you're gonna be using. This is why everyone recommends either a multimeter or ohm meter so you can measure resistance. Remember that the higher the number, the higher the resistance, and the thinner the wire's gonna be. Here's a good example from SuperX:
The same 10 wraps on the thinner 30 gauge has much higher resistance than 10 wraps on a thicker 27 gauge. So if you're using 30 gauge and you only want .8 ohms, then you can approximate that it's gonna take about 5 wraps instead of 10.
-ALWAYS MEASURE THE RESISTANCE OF YOUR COIL BUILDS
MOST IMPORTANT IS TO KNOW THE MAX DISCHARGE RATING OF YOUR BATTERY AND OHM'S LAW
- Get your batts from a reputable source (rtd vapor, etc.) and stay away from ebay
- Get IMR batts w/ high max discharge ratings like the 30A sony 18650vtc4 ( the higher the discharge rating, the lower coil resistances you can build)
- Play with the ohm's law calculator
- google, google, google

use the meter and put one lead on the resistance wire, and the other lead on the wire one inch away.
that measurement tells you how many ohms per inch the wire is.
it would be somewhere around 1 ohm per inch.
how many wraps: it typically seems to work out somewhere between 5 and 8 wraps. But I don't build coils frequently so I'm not talking from experience here, just from what I have seen here on this board.

What i think about what? I have 18650 batteries already but I don't know what amp they are? Sorry if these are dumb questions but i don't know that's why I'm asking
Thanks for this info.
I have a multimeter but I wasn't aware that you could directly measure the Ohm resistance of the coil. I thought that the resistance as measured wouldn't reflect the actual designed resistance.
I meant because you wrote:
But 28 gauge ? what would that have to do with multimeters or batteries..... nothing.
Yes the resistance is measured by multimeter; you just need to check first what you meter reads for zero resistance first then subtract that from measurements.
Oh, i was looking at the pictures of the different gauges of wire and what oms the where reading. Asking about if a multimeter telling me what amps my batteries puts out was just a question
Reputable dealers usually display a complete spec of the battery or just do a google search for your battery
For example:
Sony US18650VTC4 2100 mAh High Discharge Flat Top
Specifications:
Nominal Capacity: 2000 mAh
Typical Capacity: 2100 mAh
Nominal Voltage: 3.6V
Discharge End Voltage: 2.5V
Standard Charging Current: 1.5A
Charging Voltage: 4.20+-0.05V
Max. Continuous Discharging Current: 30A
Internal Resistance: 12 milli-ohms
Dimensions:
65.00mm (L) x 18.20 mm (D)
Weight: 45.1g
Study up on the ohms law, there are plenty of calculators out there that will assist you in maintaining your safely. You need to make sure that you battery can support the amps that you are going to required based on the resistance. I urge you to go and study up on ohms law.
What is a good gauge for Kanthal to get the most flavor and a semi warm vape? what ohm should I be looking for?
No problem at all, also be careful where you get batteries and delicates from, some places have poor quality control and a bad battery or battery with the wrong label on it can be really bad. Reviews will lead you in the right place, also lots of great threads on here as well, hope all goes well.
