then you would add 50% 50mg nic juice to 50% VG to give you a 50/50 mix at 25mg.
Now you still did not answer my question on what U are trying to achieve? Throat hit or VG dilution.
Some want more throat hit, some don't. When dealing with % mg, the more mg the greater the throat hit, therefore the less PGA needed eg alcohol. I don't use either PGA or water in my mixes. If you want an ending 60/40 VG base, then the number you plug into the calculator for VG is 40. The remaining %s will come out of the PG required to add to the mix.
to make 30 mls 24mg 60/40
14.4mls 50mg PG base nic juice 48%
0.6mls PGA or vodka 2%
12mls VG 40%
3 mls Flavour 10%
by increasing the PGA to 5% your final streght is also decreased
to make 30 mls at 5% alcohol = 22.5mg 60/40 @5% PGA
13.5mls @50mg 45%
12mls VG 40%
2mls PGA or vodka 5%
3mls Flavour 10%
PG provides a base for greater flavour, whilst VG provides a base for greater vapour.
PG provides throat hit, VG diminishes throat hit and flavour.
Alcohol will also provide a greater throat hit at the cost of vapour and flavour.
Water allows dillution of VG without adding alcohol, for those who do not like a strong throat hit, it also assists in vapour production
You see your Q wasn't simple after all
