help diluting 24mg to 16mg ???

[whatagem]

Been a while since I visited the forums & there's a LOT to sift through here!

Wondering if anyone can direct me to some good reading on exactly how & to what ration do I use to dilute a 30ml bottle of 24mg liquid to cut it down to 16mg?

And exactly where do I get Propylene Glycol? Food or pharmacy area of the store and where might it be in that area?

Thanks so much in advance for any advice!!!

Good grief! Looking at that thing is worse than high school algebra. Anyone got anything easier to look at?

Just need to know how many ml of water & pg to use in a new empty 30ml bottle

16 / 24 = .6667

Convert .6667 to a percentage by multipling by 100

=> .6667 * 100 = 66.67%

So to make any amount of 16 mg juice, use 66.67% 24mg and 33.33% of PG or VG

For your example, you want to make 30ml of 16mg juice;

66.67% of 30ml => .6667 * 30 = 20ml (Use 20ml of your 24mg e-Juice)
33.33% of 30ml => .3333 * 30 = 10ml (Use 10ml of either PG or VG)

If you want to dillute the entire 30ml from 24mg down to 16mg just do this;

30ml / .6667 = 44.99ml (This is going to be the total amount in ml)

44.99ml - 30ml = 14.99ml ( Add 14.99ml of PG or VG )

So if you add 14.99ml of PG or VG to 30ml of 24mg will give you 44.99ml of 16mg


The key is to find the ratio of what you have to what you want first. In your example .6667 is the ratio of 16mg to 24mg.

BTW - Remember when you were in this H.S. Algebra class? Remember when someone would get frustrated by the math? And do you remember someone saying;

"Why do we have to do All this Math? When are we Ever going to have to use it?"

Now you know.

Does anyone know where I can buy PG in small amounts, like 30 ml? On second thought, if I wanted to reduce the nicotine without affecting the flavor, this wouldn't work, would it? Not all flavors are available in 0 nicotine, so how would I reduce the nicotine in 'Dunhill' flavor to zero nicotine, or is it even possible? Thanks!

 

[zoiDman]

Yeh, Anytime you add a non-flavor to an e-Juice to reduce it's mg level, you Also reduce the flavor.

Hence the need for Flavor concentrates to boost the flavor back up. It also involes a little more math than shown above.

 

[whatagem]

I personally don't care about the flavor. Thanks for the math up there though....I'm gonna sit & stare at it for a while.


I was never one who said "Why do we need all this math?" (though I do not use much math in my daily life!!!)
I ALWAYS was one to complain about english class. To this day I still have never had the urge to draw a rocket ship & diagram a sentence!

 

[whatagem]

Also, I add only PG....no water? I thought most liquids had about 20 to 30% percent water. Not sure where I heard that....

 

[four2109]

You can get PG by the pint at your pharmacy. They will probably have to order it but you should get it the next day. Ref water, you are probably thinking of VG. It's thicker and many people dilute it with distilled water.

 

[whatagem]

They don't have it on the shelf at a pharmacy like CVS or Wal-Greens? Ech, I hate standing in line at the pharm counter! Thanks for the tip!!

The Math I can do well. But I Kant Spell Wurth a Darm.

The key when you go to mix of dillute is to find the percentage of the thing you are starting with to what you want to end up with. I left the answers in decimal form so it would jive with you and your calculator. Most people, includeing myself just round them off to make it easier.

So If I was doing it, I would just say: I'll use 67% 24mg and 33% PG or VG.

Also remember that 1ml = 20 drops (Roughly)

This is very handy because 5ml = 100 drops. 5ml is a nice size to test things out with. And the math becomes simple too,

67% of 100 = 67
33% of 100 = 33

So if you put 67 drops of your 24mg juice into a bottle and then added 33 drops of PG or VG, you would end up with EXACTLY 5ml of 16mg juice.

The cool thing about drops is that you can buy 3 packs of eye dropers at you drug store for like $2.00

A lot easier for small batches than buying a bunch of ser-rin-gises(sp?) and trying to measure out things.

Thanks so much, this is all very helpful & easy for me to understand.

I hate math--i mean I really hate it!! I was always naturally good at english and it bored me to tears. ESPECIALLY the stuff nobody ever needs (like that stupid rocket ship)

My mother chastised me when my nephew needed help with writing 20 poems in his HS class. I told him, "Just write whatever. It doesn't have to rhyme and you will never, ever do this again for as long as you live!"

Was that so wrong? He wants to be a big rig mechanic. I doubt he'll need much poetry there. What does a 16 yr old boy do with poetry anyway? I'm a girl and even I hate poetry

I teach low level math at a community college. Everyone I have in my class say the same thing. "I hate Math."

What I find is that most don't really hate math. They hate the fact that they can't do math when others can.

I feel sorry for people coming up thru the public school systems when it comes to math. The schools don't have the ability to hold a student back in a math class. So if a student ever starts to fall down in math at a lower level, they never really get it before they move on to a higher level.

Math constantly builds on what you have learned earlier. It you slip at any level you arn't going to be able to do well at higher levels.

I believe that if math was taught more on the idea of when you understand and can pass a certain level, you the move to the next. If you need to keep doing say ratios or algebra or trig until you get it, no problem. But the grade and H.S. just push kids onto the next level.

I think if you get out a pencil and some paper and work this mixing problem out a few time and for a few different mg levels you can master it in about an hour.

And if you get stuck or have another question, post it here on the ECF.

I agree about public schools. I had a football coach for algebra & geometry. I tried, I really did & this coach knew this. The problem was the teachers were set on such a pace that we had to learn a new thing in those classes every single day. By the end of the class I had it down & understood it. The next day, it was totally gone. Finals were a nightmare.

Admitidly, if it didn't interest me, I'd do enough to barely pass and math was no exception. My Algebra II final was all I needed to graduate & after I finished the test, I knew in my heart I had failed. I stopped back by and Coach told me I had passed--though he never let me know of a grade. Then I was really sure I had failed!

But he passed me because he knew I studied, actually tried, and that was something I didn't do in a lot of my other classes.

While I agree that most basic math can be taught & learned, sometimes it's just not for that person. I'm no good at math, but I'm not good at lots of things. Though I'm good at other things that come naturally or with practice. I always considered myself math-dyslexic because all I see are numbers, rows of numbers! But I also look under the hood of my car and see nothing but wires and hunks of metal.

Fortunately, I never aspired to become a scientist

I knew what you are talking about. Your on a treadmill and if you fall off, even just briefly, its Very difficlut to get back on.

Sometimes I wonder if it would makes more sense to have 2 tracks in math given at the H.S. level.

Track 1 is purely for college prep. Basical the same as the give currently in H.S. Algebra, Geometry, Trig, Pre Calculus.

Tract 2 is for non college graduates. Algebra with practical applications, Geom & Trig Practical applications.

It would seem that instead of grinding away at some math issues that many students will not use for higher levels of math, perhaps more time should be spent on doing real life problems.

Sometimes just being in a smaller classroom and getting a little more one on one help can do wonders for Anyone with math.

Are you ok on the mixing and dilluting stuff here in this post? Like I said, if you have a question, don't be afraid to ask.

Well, no. You can get 120ml, which is about 4 ounces.
