What's the difference between % and mg/ml nicotine strengths?

The nicotine strength of an e-liquid may be displayed as either mg/ml (or just mg), or as a percentage. Mg/ml shows the amount of nicotine per milliliter of liquid, and a percentage figure shows the amount of nicotine as a percentage per total. These measurements are the same across e-liquids, pods and cartomizer refills.

For example:
  • A 12mg e-liquid is the same as 1.2% - this would contain 12mg of nicotine per milliliter of e-liquid. 1.2% of the liquid is nicotine.

  • A 3mg e-liquid is the same as 0.3% nicotine

  • A 6mg e-liquid is the same as 0.6% nicotine

  • An 18mg e-liquid is the same as 1.8% nicotine

  • A 24mg e-liquid is the same as 2.4% nicotine
