Steam Engine VG/PG Ratios

[Sprite71]

New to mixing so this might be a bit dumb.

In the following calculation I would have expected to be using 50ml VG (including the nic) and 50 ml PG for a 50/50 mix but it’s actually 56 ml VG and 44 ml PG. Is this right or am I misusing the calculator.

ok I’ve got it (I think) it’s only 28% of the nicotine mix that’s VG (72% nic) so 12 ml is ignored and only 4.67 counted

.... but what it should have been is this

.... guess who has used up all their nicotine and created all the wrong ratios

I shouldn't worry too much - I think you are at 44/56 PG/VG with the first one.

It’s not too far off, so still usable. I’ll know for next time

No, that’s not how that works. 72mg nic is 7.2%, not 72%. So you want to put 7.2 and 1.2.

Yes as soon as I’d typed it it I was like whaat, that doesn’t sound right ... I’d worked out what I’d done by post #3. The quantity of nic to add looked right (which it was) so didn’t notice it at first.

I don't get why neither of your PG quantities is 50ml? I must be missing something but if you've put in that you want a 50/50, your PG quantity should just be a straightforward 50ml

Take 1.2 ml out of the VG nic quantity (which is the amount of nicotine contained in the 7.2%) and ignore it ... then it works out 50/50. That’s my assumption anyway

That’s true, it only makes 99.4ml, the recipe.
