Being new to vaping (a week), and *really* new to mixing (waiting for my flavors to arrive), I looked around on the forum but didn't notice references that gave an indication of how much flavoring liquid was needed in order to flavor a 30ml bottle of e-liquid. So this is my attempt at such a thing. Hopefully my math is correct and someone can validate
This is all based on the rule of thumb that 20 drops of liquid is the equivalent of 1ml. It seems accurate enough and hopefully it helps save some people the agony that is mathematics.
Estimates on the amount of flavoring needed to flavor a 30ml bottle of e-liquid are based on the forum calculator's default value of 12% flavoring in their mixtures.
I do not take into account the addition of distilled water or vodka in this post, as the amounts required are so small. So if you do add water, vodka, or other additives like that juice doctor stuff (can't recall it's actual name at the moment), total yields will be slightly higher.
20 drops / 1 ml
100 drops / 5 ml
600 drops / 30 ml
If you wish to keep your e-liquid the same strength right out of the bottle (not going to dilute it at all with glycerine)
72 drops (3.6ml) of flavoring will be needed to flavor the entire 30ml bottle of e-liquid, yielding about 33.6ml of e-liquid for use.
If you dilute your e-liquid to 1/2 strength using glycerine:
144 drops (7.2ml) of flavoring will be needed to flavor the entire 30ml bottle of e-liquid, yielding about 67.2ml of e-liquid for use.
If you dilute your e-liquid to 1/3 strength using glycerine:
216 drops (10.8ml) of flavoring will be needed to flavor the entire 30ml bottle of e-liquid, yielding about 100.8ml of e-liquid for use.
Hope this helps in some way for other newcomers. This gave me a really good indication as to how much flavoring one should have on hand, and could help others avoid having too much flavoring liquid on hand... wait... that's not even really possible is it
