Easiest equation for figuring out your nic ratio.

[lovemytank]

This has probably been posted already but I hope to make it easier.

1. Take your mg of nic base say 36mg
2. Take your mg desired nic
3. Divide #1 by #2
4. This give you total units
5. Subtract 1 which will be your nic
6. The rest will be your VG or total non nic VG/PG base

Example: 36 mg nic and I want 6mg nic juice. 36 divided by 6 = 6 so I have 6 units.
Subtract 1, so I will have a ratio of 1 part nic and 5 parts non nic base.
If I want to end up with 24 ml of unflavored nic juice (leaves some room for flavoring in a 30ml bottle), I divide my total 6 units into 24 = 4.
You will then use 4ml of 36mg nic and add 20 ml of your non nic base.

Easy, I hope. Im pretty jazzed not to have to figure it out each time now on paper. ejuice calculators are great but I really prefer to do it like this since it is pretty basic. Thanks for reading.

Tell me one more time.
I have 18mg/ml nic, and I want 12mg/ml nic, how do it do it?

18/12 = 1.5 units - 1 = 0.5 parts non-nic to 1 part nic. So lets say you want 24mL like the OP, 24/1.5 =16, so you will want to do 16mL of your nic base to 8mL of non-nic base.

A= total amount of juice, in ml, that you want to make.
B= number of mg/ml of nicotine that you want in the final juice.
C= number of mg/ml of nicotine in your nicotine base.

Multiply A times B, then divide by C. That will yield the number of ml of nicotine base to use.

example: I want to make 30mls @ 12mg/ml and I have 48 mg/ml nicotine.

30 X 12=360 divided by 48 = 7.5 mls of nic

I'm not a math whiz so this formula is the simplest one I have found.
