Crap at maths, bit of help

[Flipside]

So I made a 100ml mix with a 1 shot flavour last night, I used 20% flavour, easy enough, if it's too strong how much Pg would I need to put in to it to get it down to say 15%.
Sorry for the dumb ass question.
I mixed it at 25/75 Pg/VG just incase it needed adjusting.

Do you want to keep the same VG/PG and nic ratios @Flipside? That will make a difference!

Hmm, nic isn't so important as it's only going to be a slight difference, I'd prefer the final mix to be closer to 30pg but 80vg wouldn't matter either, that's kind of why I did a 25 75 mix.

You used 20ml flavour in 100ml of juice, giving you 20% flavouring.

To take that 20ml of flavouring down to being only 15% of the total you need to add 33.33ml of VG/PG.

I.e 15% of 133.33ml is 20ml.

 

[scrumpox]

100mls at 20% flavour would be 20mls of flavour
For 20mls to be 15% of a mix you need to add 33mls of diluent
That also drops your nic strength ... what strength/ratio do you want to end up with?

 

[Flipside]

I use 3mg nic usually and would want the final ratio to be no less than a 70/30 VG PG.
My nic is VG 72mg.

You need:

1.3ml nic
24ml vg
8ml pg

This will keep everything else the same but reduce the flavour to 15%.

Awesome thanks!
