48mg pg then cut it with vg (or vice versa). Example: 50% pg nic juice cut with 50% vg. If you are using a 10ml bottle then it would be 5ml of each to get 24mg. If you're adding flavoring, lets say 1ml of flavoring, then to keep the 24mg, go 4.5ml pg nic, 4.5ml vg, 1ml flavoring. This makes a 50/50 ration. Just tweek it how you want it. There are some good ejuice calculators floating around on this forum as well. I like more vg than pg due to alleriges to pg. All of my nic juice is pg at a higher nic strength. That way my finally result will be more vg than pg once I cut it down to my nic level.

50/50 is not very thick compared to 100% VG. Since your VG % is higher, you would have to go with a VG or 50/50 blend to make the desired e-liquid.

To get 24mg from 100% PG for a 60%VG 40%PG blend would not be possible from a 48mg PG unflavored base.

Thank you for pointing that out, I was reading it backwards @ 60/40 PG/VG.

Ok I'm going to be jumping in to DIY and this may be a stupid question but here goes, So lets say I want to end up with e-juice that is 40%pg, 60%vg at 24mg nic. Which unflavored nic juice do I buy? 100%vg, 100%pg, 50vg/50pg??? :confused: Thanks guys/gals

I left you an answer to your question in the post you made today on the eJuice Me Up StuckinLA

RedneckHipppy, What percentage do you want in the final mix, and how many mg/mL nic are you using?

I'm using 60mg/ml Nic juice with 50/50 pg/vg. I suck at math so was wondering what the formula would be for various mgnic. I'm just starting and want to be able to change dosage of nig and/or vg/pg mix til I find one I like.

For Redneckhippie, so I can tell you how I would do this but it's not simple. If it totally doesn't make any sense I can type it up using an equation editor tomorrow morning and make it look clearer on the page. I'm going to step through an example using easy numbers so it is clearer. For this example your going to make 10mL of juice that is 20mg/mL nic and has 50%PG and 50%VG as the final mix.

You have unflavored nic at 60mg/mL. To find out how much of the nic liquid to use, divide the desired 20mg by 60mg to get .33 or 1/3. One third of 10mL (target amount) is 3.3mL so that is how much nic juice you want to use for 10mL at 20mg/mL.

You are using a 50/50 nic mix so 1.65 of the 3.3mL is PG and 1.65 is VG. I keep a running sum. Write one column for PG and one for VG. each column has 1.65 in it now. In the end both the PG and the VG column should add to 5 so that 5mL of VG plus 5mL of PG will equal 10mL of juice.

Now for flavoring. Most Flavoring is PG based, so whatever percentage of flavoring you are going to use put a decimal point in front of it and multiply that times 10. So for this case I am going to use 20% flavoring in my juice. 20% of 10 is (.2*10=2) 2. So 2ml of flavoring goes into the mix, and 2mL is added to the PG column(assuming that it is PG based flavoring).

Now my PG column is 3.65 and my VG column is 1.65. All I have to do is subtract 3.65 from 5 to find the amount of additional PG that I need and subtract 1.65 from 5 to find out how much VG I need to add.

5.00 - 3.65 = 1.35 mL PG 5.00 - 1.65 = 3.35 mL VG

Add those to the mix and your done.
Now I used 5 because it is 50% of 10. If you were doing a 60PG/40VG mix ( as a final product) it would be
6.00-3.65 =2.35 4.00-1.65=2.35
because 6 is 60 percent of 10 and 4 is 40% of 10.

If you want to add distilled water or PGA to thin it that will change the calculations a little. If I want to add 10% water in this instance, 10% of 10 is 1. So instead of my columns needing to sum to 5mL each they now need to sum to 4.5 mL each. You don't have to use any distilled water or PGA if you don't want to. If you are using a lot of VG, the juice will be pretty thick and might not wick fast enough.
Hope this helps.:)

GoodDog, thanks. It's nice to see that vaping kitty.

The one thing about the above is that I take the % water from the whole quantity. I mix for a 50PG/50VG end product and I end up with wicking issues because I chain vape. I use a lot of water in my mix to thin all that VG so my atties don't burn. I don't know if is standard to take the percentage of the whole or just the VG. If you were using a lot of PG and you did it my way your juice could be too thin. So if the juice on the first batch ends up too thin just decrease the percentage of water/PGA used.

After reviewing this thread I thought I might lend a pratical excel sheet to help in the figuring process. I have attached it to this msg and would like you to run through the process for me and check my figures. I did make the VG = 100 - the PG amount so you only have to set the PG amount of the base nic and the VG will auto populate.
You think I ought to add it to the main calculator?

In the above calculations we are adding H2O to both PG and VG, why? Only VG needs to be diluted, no? Diluting VG at 20% with distilled H2O renders a viscosity similar to PG.

Returning to the original question, why buy a mix? The easiest way to mix is to buy 100% PG nic and go from there (easier to work with). IMO the more calculations involved, the greater chance for errors.

Not everyone has your insight. And not everyone thinks about buying straight based liquids. Me I preferr them, easier to mix and calculate. The only reason water was split in the above calculator is to show how it is dispered if used and for calculation purposes. That way you stick to the defined percentages of PG/VG. If your using high VG% then yes use a little water, otherwise it is not needed.

Dan,


I cannot thank you enough for this little sheet it is exactly what I have been looking for! I have different people I mix for that ask for different ratio's and this will save me so much time and headache because I suck at math so bad LOL.


BTW: I use you calculator daily and IT ROCKS!!!!


Thanks Again!
Mary
