Mixing dilemma

[ScottyMeaty]

I assume this is where to ask....

I have been adding my own VG/PG/NIC to premade flavours for years. I usually go for 70/30 + 3mg nic (using 72mg)
My problem is my supplier has given me a high VG base mix. (93%VG/7%PG)

I cannot figure out the correct ratio,

To make using 25% concentrated flavour into:
250ml (total)
3mg nic (from 72mg)
70vg/30pg

Am I being stupid or is the calculation that complicated...

Please help if you can, I have seven bottles to make and cannot do it....

Many thanks!!!!

Is the nic in PG or VG? Welcome to POTV

Thanks!
The nic is PG

Thanks for the reply, unfortunately this calculator does not take into account that the bottle I have is already premixed (93%VG/7%PG). This is the dilemma or lack of mathematical knowledge on my part..

That’s a very odd pre-mix ratio

Yep, I thought that too, but. Did you try the custom tab. That allows you to put custom ratios, in the field.

I thought that too. But decided to work with what the OP said.

*Edited as I think I misunderstood originally.

250ml - 62.5ml Flavour(PG) - 10.42ml Nic (PG) = 177.08ml

7% of 177.08ml = 12.4ml PG in base

PG Total = 62.5 + 10.42 + 12.4 = 85.32ml

85.32 ÷ 250 = 0.34128

65.87VG/34.13PG

I think that base mix will make your overall PG a bit more than 30%. I don’t know how to use any of the calculators with pre-mix though, this is the exact reason I always have VG and PG separate.
