Mixing pre made concentrates

[tonyb]

I've bought a few bottles of premade concentrates, they recommend mixing at 20%.

I also have 7.2% VG nicotine and a bottle of VG.

I want to make 50ml of ejuice using one bottle of concentrate which is 10ml.

I tried to figure this out using an online calculator but I'm not sure I'm entering quantities correctly. Target ejuice strength is 6mg.

How much nicotine and VG do I need to combine to get my 50ml of 6mg juice?

Is this correct?

4.2ml of 72mg/ml nic + 35.8ml of plain VG +10ml flavour = 50ml eliquid 6mg/ml nic (20PG/80VG)

I'm not sure why your calculator is saying to add 10ml PG
Most calculators assume (or let you specify) flavour as PG.


[ETA] I've taken a look at your calculator and you've selected flavour in VG. If not specified on the flavouring the flavour concentrate will likely be in PG tonyb :

Thanks Postmodern Smoking - User error on my part with the VG/pg flavour
