Help with ratios

[SJvape]

Hi apes, need a bit of tutoring. Ive got pre mixed 85vg 15pg, and i want to work it out that i have 70/30 end result (higher vg is fine) but i cannot find a calculator that has the option to input pre mixed pg/vg.

Im doing some experimenting with concentrates 10% to 20%.

What would the be the best method for me to get accurate results?

Thanks

Just add 15% flavour and your at 70/30 assuming your premix has nic

Work out the total of your pg based additives and vg based additives - if your nic is pg based this will simplify things.

Let's say you are using 12% flavourings and 4% pg based nic. This equals 16% - subtracting 16 from 100 will leave 84% base, which is 85% vg, so 84*0.85 will give you 71.4 vg.

My mix is nic free. I'll be adding 72mg pg base

In that case Ment's above advice is correct, depending on what you want the final nic mg to be.
