Confused about ejuice strengths

[MaiTaiMary]

I need something explained to me about stated mg strengths.

If I buy a carto that states 18mg, I understand that to mean that the entire carto contains 18mg nicotine.

If I buy 30cc(ml) of a flavored ejuice whose strength is listed as 18mg, does that mean I would need to vape the entire 30cc to equal the nicotine in one of the above cartos? Or is that 18mg/cc(ml)?

Thanks

No. It's mg per ml. That means that if you order 30ml (or 5ml or 15ml) of 18mg nic strength, that's it...no matter whether it's in a cartomizer, or a cart, or dripping on the atty. The 18mg. carto could be refilled many times out of that 30ml bottle of 18mg juice.

Got it. Thanks. I thought that was the case but never saw it expressed as mg/ml, just mg.
