The nicotine strength of a product may be displayed as either mg/ml (or just mg), or as a percentage. Mg/ml shows the amount of nicotine per millilitre of liquid, and a percentage figure shows the amount of nicotine as a percentage per total. These measurements are the same across e-liquids, cartomizer refills and disposables. For example:
● A 12mg e-liquid is the same as 1.2% - this would contain 12mg of nicotine per millilitre of liquid. 1.2% of the liquid is nicotine.
● A 18mg mg disposable e-cig is the same as 1.8%
● A 30mg cartomizer is the same as 3% Not sure which strength to choose? Click here for advice.
