No, that's not correct. E Liquid strengths are measured per ML. A 10ml bottle that is 24mg in strength contains 24mg per milliliter. You get about 1MG of nicotine per analog usually; but, this depends on the analog.
If you're using 1ML a day at 24MG that's equal to 24 analogs. I go through about 3ML a day at 16MG (16MG x 3ML=48MG/analogs). I was only smoking 3/4 a pack of analogs a day so my intake of Nicotine is way higher with an eCig than it was with analogs.
Furthermore, it doesn't matter how much liquid is in a bottle, the strength is not dependent upon volume. That also means a 10ML bottle of 24mg juice would have 240mg of nicotine in it (24MG x 10ML). Likewise, a 30ml bottle of 24mg e-liquid would have 720mg of nicotine in it (24mg x 30ml).
