Yeah, but I'm the one who did that chart. For some reason, I think what's hanging everyone up is figuring out how many "parts" they have as in "1 ounce of e-liquid plus 2 ounces of doubler equals 3 parts to the mix." That's not math or arithmetic.For future reference bub, there is a chart on the FAQ page for tackling this sort of thing (generously calculated by one of our customers) so you don't have to delve into a former mathematics class to come up with Nic Liquid + Doubler = Target Nic ratios.
If the FAQ page doesn't answer your questions, THANK GOD FOR TECHNOLOGY, we have an 888 number and Live Help to help you tackle these important issues so you're not resolved to waiting for a reply on ECF for your "important" questions.
Quit playing helpless, use the tools at your disposal.
And there's also ChainVapor's spreadsheet which will calculate MG and VG at the same time. Search for his posts in this thread.
