Hey guys, I'm drawing a complete blank and have confused myself with nicotine percentages. I vape 6mg nicotine and have been crafting 30ml bottles. I've been using a program called eJuice Me Up. Per the calculation, I'm suppose to be using 1.8ml of 100mg nicotine solution to reach 6mg nicotine. If I plug this into a calculator, the equation is .06 * 30 = 1.8ml. I've been vaping this and haven't noticed any difference between a store-bought juice @ 6mg and the one I'm producing @ 6mg.
Now, I was reading a thread on nicotine percentages and people are converting 24mg nicotine to 2.4%. That would mean the same 30ml bottle I'm making, but at 2.4% would come out to .024 * 30 = .72ml of nicotine solution @ 100mg nicotine. If I were to follow the program I use, 24mg would equate to .24 * 30ml = 7.2mg of nicotine solution.
I can only assume the math in the thread I was reading was incorrect and 6mg mean 6%, while 24mg means 24%, both of which are using a 100mg nicotine base.
Is the program I'm using wrong? If so, I'm surprised I haven't noticed a huge difference in nicotine.
EDIT: /u/Botboy141 cleared it up for me. The nicotine I'm using is 100mg, so 10% nicotine and 90% base. This explains the difference between the decimal points.
The easy math is this:
Nicotine is calculated using mg/ml.
Your 100mg/ml solution is in fact 10% nicotine, 90% base.
If you want a 6mg/ml result in your juice, that is 0.6% of total volume but 6% of your juice needs to be your 100mg/ml base solution. 1.8ml is correct.
If you want a 6mg/ml result in your juice, that is still 0.6% of total volume, but now you are using a base that 4.167 times weaker than your 100mg/ml solution. This results in requiring 7.5ml of 24mg/ml solution in a 6mg final mix @ 30ml batch size.
Another way to think about it:
100mg/ml = 10%
24mg/ml = 2.4%
You want a 0.6% end result.
(0.6 / 10) * VOLUME = ML required by volume for 100mg/ml (1.8ml in 30ml)
(0.6 / 2.4) * VOLUME = ML required by volume for 24mg/ml (7.5ml in 30ml)
Hope this helps to clarify and not confuse further.
I think your are confusing yourself
.06 * 30 = 1.8mL of 100 mg nic
.24 * 30ml = 7.2mL of 100 mg nic
Right, but this post is what confused me:

Vaping does not deliver nicotine the same way. In cigarettes, nicotine is delivered into your body via ammonia, which is why you feel the nicotine "surge", when taking a drag.
In vaping, there is no ammonia, so, while you get the nicotine, you don't feel it immediately.
I think 24mg (2.4%) is too high for you. That's why you're getting the sore throat. I smoked a pack a day, and started with 6mg (.6%), but I think it was too low.
Might I suggest trying a 12mg (1.2%)?
Desired strength x ML Divide by your solution strength, Ex. 6x30=180÷100=1.8ML
