Mixing 2 nic strengths to get a third
Hi I'm new to this forum and just need some advice please. I've been vaping 1.2mg ejuice and have recently bought some 100mg strength mixing juice. How many ml of the 100mg mixing juice do I add to 30 ml of 11mg juice to make it 18mg strength? If Anyone can help me with an answer that would be great. Cheers

oo, tricky ..
30ml of 11 has a total of 330mg nic..we can express the quantitys as ..
(30*11) + (x*100) = y*18
y= x+30
x is how much 100 we need and y is the resulting total qty.
solving for x ..
330 + 100x = 18x + 540
82x = 210
x = 2.56ml
so add 2.5ml of the 100 to the 30ml bottle and tadaaa..

Way to confuse the poor newbies!
There is an easier way to work it out. 1 ml of 100mg/ml in a 10ml bottle gives you 10mg/ml, put it into a 30ml bottle & divide 10mg/ml by 3 = 3.33mg/ml.
So every 1ml of 100mg/ml added to a 30ml bottle boosts the nic content by 3.33mg/ml.

Sure it does.
3.33mg/ml + 3.33mg/ml + 3.33mg/ml = 10mg/ml, that's 3 ml of 100mg/ml in 30ml which is the same as 1ml of 100mg/ml in 10ml.
No need for algebra when simple addition, multiplication, subtraction & division work fine
EACH 1ml boosts the nic content by 3.33mg/ml or adds 3.33mg/ml to the total mg/ml (Edit: in a 30ml volume).

i see you sussed it in the edit .. i would rather give 100% correct info which my method, though clunky .. will do.
getting it wrong with 100mg/ml nic is not a good idea, yes using what you did will only be out by a little, but the amount it is wrong by varies with both nic strengths and bottle size.
i might be confusing them, but i answered the question 100% correctly .. you have not, went on to tell me it was confusing, gave a wrong method with no warning that it has errors. now you are defending it .. with more wrong info.
you are adding to a 31ml solution, then a 32ml solution .. what if you had 20ml of 12 and wanted to add 24 to it to get it up to 20 .. try your method and let me know the answer..

Stoney,
In your formula 330 + 100x = 18x + 540, where did you get the 540 from?
You lost me as you cant use 30*18 because the end product is (x+30)*18
My head hurts
My wife always forgives me when she is wrong.

(30*11) + (x*100) = y*18 (1) .. this is the amount of nic in each portion, the first bit is 30ml of 11mg. the second bit is an unknown amount of 100mg, the last bit is an unknown amount of 18mg nic
y= x+30 (2) .. this is the original 30ml nic + our unknown amount of 100mg nic makes a new total amount of blend made up of the 2
x is how much 100 we need and y is the resulting total qty.
solving for x ..
330 + 100x = 18x + 540
82x = 210
x = 2.56ml
so add 2.5ml of the 100 to the 30ml bottle and tadaaa..
added some bold bits above to make it easier to follow .. i hope
and this is the 540..
expanding .. stick formula (2) in for y
(30*11) + (x*100) = (x+30)*18
330 + 100x = 18x + 540 so the 540 is derived from 540 = 18 * 30 (i hope)

My method isn't wrong at all. 1ml of 100mg/ml adds 3.33mg/ml nic per ml in a 30ml volume simple, easy & correct. My edit was for clarification because I knew you were going to bring up that point that 30ml +1ml etc etc, to try to prove you were smarter than me
Edit: "what if you had 20ml of 12 and wanted to add 24 to it to get it up to 20 .. try your method and let me know the answer.."
12 what? , 24 what? , 20 what? simply putting numbers up without qualifying them by ml or mg/ml, means nothing.
