A friend allergic to pg has asked if i can make a batch of liquid 0nic at 15% he has 90ml of concentrate but i cant work out on my calculater how much vg is need to use the full 90ml of concentrate any help appreciated

[catface26]

Is the concentrate VG based?

As the flavouring will likely be PG based, max PG/VG ratio is 15%PG/85%VG , could make up 600ml with 90ml of flavouring at 15% and by adding 510ml plain VG



[Edit to Add] - If the flavouring is in VG, you still need to add 510ml plain VG to achieve 15% flavour, but your PG/VG ratio would become 0%PG/100%VG

Or you could manually calculate it:

15% of the eliquid is 90ml
100% of the eliquid is 90ml X 100/15 = 600ml

As only VG is being added, the amount of VG required is (the total amount of eliquid) less (the amount of flavour) = 600ml - 90ml = 510ml
