Question about changing PG/VG mix of ejuice

[RickCain]

So I am going to change the PG/VG mix of a bottle of ejuice bought at a store. Currently it is a 30ml bottle of 70PG/30VG @ 6mg nic.

In order to change it to 70VG/30PG @ 6mg I am assuming the correct way to do it is create a 6mg VG base and combine 40ml of my base with the contents of the bottle. According to the ejuice calculator I have it should end up the correct mix - only thing it doesn't take into consideration is the nicotine level of the VG being added.

Let me know if I am on the right track.

30 + 40 does not get you 70% and ejuice Me Up has the calculator you want just for this.

Here's how I would do it -

70% PG means that you have .7 x 30ml, or 21ml of PG

to get to 30% PG, you calculate what 21ml would be 30% of - 21=.3x, where x is the total ml you need to end up with

21/.3=70ml total

70ml total less the 30 you have equals 40ml of VG to add - You are correct!
