calculating in flavoring

[donnah]

I thought I had a handle on this diy thing and then I read where someone told someone that they need to cut their nic from 36 to 24 or they wouldn't have but 8% left for flavoring. I use an online diy calculator and I thought all I had to do was put in the percentages I want and it would figure out the rest. I'm using the ejuice calculator from ecigexpress, I've tried to run the ejuice me up calculator but it won't run on either of my computers (and they are up to date). I have 100mg.ml unflavored nic in a pg base.. I'd like to mix at 90pg and 10vg with maybe 20% flavor... does anyone have any suggestions? Thanks!

That calculator does compensate for the flavorings. The problem you mention can come in when you can't achieve the PG/VG ratio you want. Suppose you have 50mg PG nic juice and want to make some 50/50. It would be impossible to do a 24mg at that ratio and still have any room for flavoring since you'd be using 4.8 ml/pg, 5ml/vg, and only have room for .2ml of flavoring (2%) in a 10ml bottle. You'd have to either use a higher PG ratio, lower the nic level, or put less flavoring.

If you've got PG nic juice and are mixing at 90/10 you should not have a problem. By the way, check your flavoring to see if it's PG or VG base. That can affect your proportions.
If my explanation isn't clear let me know.

Thanks for the reply! That clears up a lot for me!

Using 100mg PG makes calculating nic amounts easy because of percentage: to make 12mg juice, use 12% of 100mg nic, for 18mg juice use 18%, and so forth.

If you want to make 18mg juice, just multiply the total recipe amount by 0.18 to get the quantity of nic to add. Example: 10 mL x 0.18 = 1.8 mL of 100mg nic needed to make 10 mL of 18mg juice.

To make 5 mL of your 90 PG/10 VG recipe with 20% flavoring and 18mg nic:

5 ml x 0.18 (18%) = 0.9 mL 100mg PG nic
5 mL x 0.20 (20%) = 1.0 mL flavoring
5 ml x 0.10 (10%) = 0.5 mL VG

Add up the ingredient amounts so far: 0.9 + 1.0 + 0.5 = 2.4 mL
Subtract that amount from the total recipe amount: 5 mL -2.4 mL = 2.6 mL of plain PG needed to fill out the recipe.

Final result:
0.9 mL . . . (18%) . . . 100mg PG nic
1.0 mL . . . (20%) . . . flavoring
0.5 mL . . . (10%) . . . . VG
2.6 mL . . . (52%) . . . . PG
