How to calculate amount PG in 36mg-20ml PG-based Nic?

[TJPatt72]

Since all my nic from 3 sources is PG based I need to have an ideal of about how much of it is PG. When making a batch and only adding in 20% VG with 80% PG in reality it has more PG in it than 80% since the nic is based in it also.

Can you use Scubabatdan's ejuice calculator to get an ideal of this amount?
If you put in like 100 mg base to make 20ml of 36mg juice and then only enter 100% PG added does that give you about how much pg would be in 20 ml of 36mg nic bought to make juice from? That produces adding 7.2 ml PG or VG with nicotine and 12.8 ml of PG/VG (no nicotine). Yes it would still be a little off due to the PG/VG with nicotine, but might come closer to what you would want to add in VG to damper the PG more and produce more smoke.

I might can help.
100mg/ml PG based nic juice is comprised of 10% nicotine - 90% VG. In a 30ml bottle that is 27ml PG, 3mg Nic.
In a 36mg/ml batch 3.6% is nicotine, 96.4% is PG.
If you play with Scuba's calculator, you can figure it out. I think it is section 3
I hope this helps you out.

Thanks supertrkre, your answer came up with what I concluded with research, yet I don't trust my conclusions . This is how I reached your same numbers with only the 1ml=1000mg coming out of a post I found:
1ml=1000mg (amounts you insert are per ml of substance; in mg. For example in 1 ml of glycerine there are 1000 mg glycerine)
20ml-36mg nic
Nic-36mg/ml=36mg/1000ml=0.036=3.6%/ml...20ml x 3.6%/ml=0.72/ml Nic in 20ml
PG-100-3.6%=96.4%...20ml x 96.4%/ml=19.28/ml PG in 20ml
0.72/ml Nic + 19.28/ml PG=20ml

Knowing that and with the suggestions to add only up to 20-30% VG without adding a thinner I guess where directed towards Nic based in VG since PG thins down the VG also. I can't use Scubabatdan's Ejuice calculator since I'm on W98SE and can't get it to download from his site anyway. Did get an earlier posted SS and plugged that into my MSWorks 8.0 and adjusted it out to work adding some to show when a batch won't work.

If we are right I can add that in to my calculations to know exactly how much PG exists in a batch, so that I can make a better judgement on how much VG to add without adding a thinner.

It sounds like you have it all figured out now.
Actually, it sounds like you have been talking to a theoretical physicist.

PM me your email and I will send it to you direct.
Also have you tried Open Office? It is free and it will open excel files, you can get it from www.openoffice.org
Here are the instructions for installing open office on Windows 98:

BTW as Levy pointed out to me, he uses the water field to determine % for VG, if you put 20% in the water field it will tell you the amount of VG to use for the mix.
