Noob to D.I.Y. Question on percentages

[guinnesstime]

Hi all. Hoping to find out how to make a 16 or 18mg juice with supplies I ordered. My main question is that I have 48mg nic that is in a 80PG/20VG Bottle.
Not sure how the calculators work if I have the nic in a blended 80/20? Any advice would be very helpful!

Not sure what the question is here...
Do you need to know how to make 18mg/ml juice from a 48mg/ml base?
Do you need to know what the final ratio of PG/VG is? (Don't know what else you're mixing with, so that's a toughie)
Do you need further instructions on how to use a specific calculator?

I'm looking to make a 18mg juice (70/30). I have PG and VG. and the 48mg juice.
I guess I'm getting confused with all the calculators- since I cannot figure out how to account for the blend of nic juice I have (80/20).

 

[Hoosier]

Ah, you're outside my area of expertise. I only use one calculator and I have just a passing interest in the final PG/VG ratio as I find it more bother than it is worth. I just shoot for "a little VG", "some VG", and "a bunch of VG" and leave it at that. (I can go back and calculate the final if I ever wanted to, but I don't since the little/some/bunch thing works great for me.)

Hopefully someone who is rigid on PG/VG ratios will chime in.

Thanks Hoosier!

If you go to 16ml it gets pretty easy. For whatever size you make, use 1/3 nic liquid (48/3=16). The VG in that is approximately 7% of your targeted batch (20%x.33), so you can add 25% VG you will end up at approximately 32% vg. The last step is to fill your container, if marked, to the targeted amount with flavorings (typically PG based) and PG and you're done. If not using a marked container, here's a formula - where B is the batch size - .33B Nic + .25B VG + .42B PG/Flav

30ml example:
10ml 48mg nic (1/3 of 30)
7.5ml VG (1/4 of 30)
12.5ml PG & Flavorings (30 -17.5)

End result - 16mg, 20.5ml PG, 9.5ml VG - approximately 68/32 pg/vg

Hope that helps!

That really does help.
So to add flavoring, I would just subtract some of the 12.5ml of PG and add my flavoring?

 

[440BB]

Yes - most flavoring will be in the 5-15% range total, just subtract from the 42%.

Much appreciated!

Now the fun begins as you start making, trying and fiddling!

Use this calculator:

eJuice Me Up - Best eJuice Calculator

It does the mixed PG/VG nic base calculations. It's a good calc, and easy to use.

Thanks much!
