help with adding more nic to juice please

[Anthony-Usa_OH]

Hello, I have close to 25ml of 12mg juice and I need to know about how many drops to make it around 20mg juice.
Thanks!

Two things:

1) That depends on the concentration of the nic you're adding.
2) Drops are a really imprecise method of measurement, when it comes to nic you should use mls to be as accurate as possible.

You can try using one of the calculators on this website--maybe the combining liquids one. As mentioned you will have to add in your target strength and strength of nicotine you are using. Also agree that the best measurements are with a small 1 ml syringe for flavorings or graduated cylinder as opposed to counting drops. You can count the drops to see how many drops it takes to reach one ml with the dropper you are using and enter it the calculator into the section that calls for how many drops makes 1 ml. The default option is usually 20 drops and thats not accurate for every dropper. Hope it makes sense.

it's 50mg nic

I found out that if I take the original number to make it and divide it from the new target you get the number.

lets say to get 30ml of the 12mg witch it is currently, it took 144 drops of 50mg nic.
I want 20 mg so it will take 240 drops, 240 - 144 is 96 more drops to make it 20mg.

Hope that it's a good way to do it.

If you are starting with 50mg nic and want to make 30ml of 20mg nic the formula is:

Nic = 12ml
PG = 18 ml

All droppers are different so you need to figure out how many drops = 1ml with the dropper you are using. I'd use a syringe or a cylinder to measure 30ml - that's way too many drops for my brain to count perfectly and not lose track.

Try reading this post and using your number instead of theirs.

When you go to Calculate the mg/ml of Nicotine it’s going to be the Total Amount of Nicotine Divided by the Total Amount of Milliliters.

Let’s forget about making Exactly 2ml for the time being.

Just think about making some amount of 24mg/ml e-Liquid out of Both 50mg/ml and 18mg/ml e-Liquids.

So the Formula is…

Some 50mg Plus some 18mg Divided by the Total Amount of 50mg Plus the 18mg Equals 24mg.

Yuk… A word Problem. Everyone Hates Word Problems. Let’s convert it into a Math Problem.

Let: X = The Amount of 50mg e-Liquid and Y = The Amount of 18mg e-Liquid

So…

( (50X + 18Y)/(X + Y) ) = 24

Most people don’t Like to work in Two Variables X & Y. So why don’t we make One of the Variables something that is Easy to work with? How about Y = 1

Replacing Y with 1…

=> ( (50X + 18)/(X + 1) ) = 24

Throw a Little Algebra on it…

=> 50X + 18 = 24(X + 1)
=> 50X + 18 = 24X + 24

Collect up some Like Terms…

=> 50X -24X = 24 – 18
=> 26X = 6
=> X = 6/26
=> X = 3/13
=> X = .23

So when there is .23 ml of 50mg e-Liquid Added to 1 ml of 18mg e-Liquid the Result is 1.23 ml of 24 mg e-Liquid.

Cool. But you want to make Exactly 2ml. So we need to add More of both the 50mg and the 18mg to get to 2ml. But How Much More?

If I Divide 2 by 1.23 I get 2/1.23 = 1.626

So it sounds like I Need 1.626 Times more 50mg and 1.626 Times more 18mg to get me to 2ml

=> 1.626(.23) = .374ml of 50mg

And

=> 1.626(1) = 1.626ml of 18mg

Hence it sounds like if I Added .374ml of 50mg to 1.626ml of 18mg I would end up with 2ml of 25mg.

I know you might be getting lost but Stay with me, this is the Important Part

Knowing how to make 2ml of 24mg is Great. But would it be Better to know how to make ANY amount of 24mg?

Once we found a Ratio of 50mg to 18mg why don’t we just Express it as a Percentage which could be used to Make any amount of ml?

Since we know that the Ratio is .23ml of 50mg to 1ml of 18mg for a Total of 1.23ml, let’s find the Ratio for 1ml

1ml / 1.23ml = .81

So if I made both the 50mg amount in the Ratio and the 18mg amount in the Ratio Smaller by .81 times, I would have a Ratio for 1ml

.81(.23ml) = .19ml of 50mg

And

.81(1ml) = .81ml of 18mg

So in 1ml of 24mg e-Liquid there is .19ml of 50mg and .81ml of 18mg e-Liquid.

Thus the Percentage for ANY amount of 24mg e-Liquid is: 19% of 50mg and 81% of 18mg

Always Double Check your Work!

.19(50) + .81(18) = 24.0 Good!

You might want to print this out because you can use this Approach for Any mg e-Liquids.

You might also want to do the Math Yourself because I have been known to make some Pretty Bad Math errors First thing in the Mourning.

If your still stuck, maybe I can tailor one for you case.

There is Nothing wrong with using Drops.

As long as you use the Same Eye Dropper for all the Liquids and the Liquids have roughly the same Viscocity.

If you are starting with 50mg nic and want to make 30ml of 20mg nic the formula is:

Nic = 12ml
PG = 18 ml

All droppers are different so you need to figure out how many drops = 1ml with the dropper you are using. I'd use a syringe or a cylinder to measure 30ml - that's way too many drops for my brain to count perfectly and not lose track.

In this case, the Nicotine is 40% of the Mixture and the PG is 60% of the Mixture.

If you work in Percentages than the Units of Measure don't matter.

40 Drops of Nicotine to 60 Drops of PG. (As long as you use the Same Dropper & the Nicotine / PG are abouet the Same Viscocity)

40 Teaspoons of Nicotine to 60 Teaspoons of PG.

40 Shot Glasses of Nicotine to 60 Shot Glasses of PG.

or as you mentioned

12ml of Nicotine to 18ml of PG. (12 & 18 are Scalar Multiples of .4 & .6 ie: the Scalar is 30)

I like to work in Percentages because once I know the Percentages, I can make Any Mixture Size.
