Higher nicotine level needed.
Can someone help me with this math? If I had 18mg juice and wanted to get it to 20-24mg. How much 36mg juice should I add? I have some medium juice that is just too weak.
Thanks

To get to 24mg, use 2/3 18mg and 1/3 36mg.

You would have to add 3ml of 48mg to 6ml of 12mg to come out to 24mg for a total result of 9ml of now 24mg juice.

The maths
The trick is to calculate the total mg and the total ml. Then divide your mg by your ml.
Here are the maths in 3 simple steps:
1) For each liquid multiply the mg value by the number of ml you will use.
2) Add the values from step 1) together
3) Divide the total of step 2 by the total of ml of all liquids.
Example
You mix 1 ml of 48 mg/ml with 2 ml of 12mg/ml with 1ml of PG/Flavoring (0 mg):
Step 1)
1 ml x 48 mg/ml = 48 mg
2 ml x 12 mg/ml = 24 mg
1 ml x 0 mg/ml = 0 mg
Step 2)
48 mg + 24 mg = 72 mg
Step 3)
Your total of ml is 4.
72mg / 4 ml = 18 mg/ml
The best is to put those formula in an Excel Spreadsheet

To obtain a specific strength from 2 different strengths, it's a little complex. That is, if you have 48mg juice and 12mg juice, but want to make a bottle of 22mg. Figuring that out in your head can be a little complex.
So I wrote an Excel macro that will get the answer.
Mix 2 Strengths Excel Macro
You enter 4 items:
- Strength of the first Nicotine Juice
- Strength of the second Nicotine Juice
- The desired strength
- Amount you wish to make
Then click the Calculate button.
A box will pop up telling you how much to mix of each juice. It will also tell you how much this will make, and what the actual strength is. It comes very close to the correct answers, but it's rarely perfect. That is, you may say you want 5ml of 22mg, but this macro may calculate 4.9ml of 21.7mg. I don't think you'll notice a difference.
It does require Microsoft Excel, and will not work in OpenOffice Calc. But if enough people ask, I can probably make it work for OpenOffice Calc.

Here are the exact math but putting it in an Excel sheet is another task...
Let me do it with your sample:
Liquid 1 is 48 mg/ml
Liquid 2 is 12 mg/ml
Your goal is 5 ml of 22 mg/ml liquid.
5ml * 22 mg/ml = 110 mg
You have to find 2 number:
the amount of ml of liquid 1. Let's call it Y
the amount of ml of liquid 2. Let's call it Z
such as
110 mg = Y ml * 48 mg/ml + Z ml * 12 mg/ml
and
5 ml = Y ml + Z ml
thus we can say Y ml = 5 ml - Z ml
and rewrite
110 mg = (5 - Z) ml * 48 mg/ml + Z ml * 12 mg/ml
We can now extract Z (this time I drop the units to keep it shorter)
110 = (5 - Z) * 48 + 12Z
110 = 240 -48Z + 12Z
110 = 240 -36Z
36Z = 240 -110
36Z = 130
Z = 3.6 ml
Now that we have Z
Y = 5 - Z
Y = 5 - 3.6
Y = 1.4
