Yes.
30ml of 12mg/ml added to 30ml of 0mg/ml would give you 60ml of 6mg/ml.
The Formula for Milligrams per Milliliters is... Total Milligrams divided by Total Milliliters.
You have,
30ml of 12mg/ml => 30 x 12 = 360 Total mg's of Nicotine
and
30 ml of 0mg/ml => 30 x 0 = 0 Total mg's of Nicotine
and 30ml + 30ml = 60 Total ml.
Plug this into the formula.... Total Milligrams divided by Total Milliliters.
360 Total mg / 60 Total ml = 6mg/ml
And this Jives with the Common
sense thinking that I just cut the Nicotine mg's in Half by adding the same amount of 0mg/ml to the same amount of 12mg/ml.

I think where people can get confused with all this is from the way we shorten the amount of Nicotine in our
e-liquids from say 12mg/ml to just 12mg.
Just remember that when you see an
e-liquid that says it is " __mg ", that it is really " __mg/ml"
Hope this Helps. And have a Good New Years.
