What Do E-Liquid Nicotine Concentration Measurements Mean?



The numbers on the labels of e-liquid with nicotine represents the concentration, or strength, of nicotine in the e-liquid.

It is measured in milligrams of nicotine per millilitre of e-liquid (mg / ml) and is often shortened to mg. The strength can also be expressed as a percentage of nicotine by mass, e.g. 12mg/ml can be expressed as 1.2% nicotine or 12mg nicotine, and they both mean the same.

A 30ml bottle with a nicotine concentration of 12mg/ml will therefore contain a total of 360mg of nicotine (30ml x 12mg/ml). If 1ml of e-liquid is equal to about 20 drops, then there is about 0.6 mg of nicotine in each drop (12mg/ml รท 20 drops). So, if you load 10 drops of e-liquid in your e-cigarette, you should be consuming about 6 mg of nicotine (0.6 mg/drop x 10 drops) if you vape away those 10 drops.

Freebase vs. Salt Nicotine: What's the difference?

The ideal goal is to match the amount of nicotine you are taking in on a regular basis through cigarettes with the milligram of nicotine in the eliquid. As previously mentioned the body absorbs about 1mg of nicotine per cigarette. With eliquid, each millilitre of liquid contains the indicated nicotine content on the bottle. For example, when using a 6mg liquid in a 4mL tank, the nicotine content of the tank is 24mg of nicotine, the equivalent to 24 cigarettes. Tank Capacity x Nicotine Content = # of Cigarettes.
