One of the coolest features of vaping is the freedom it gives to users to select the strength of nicotine of their e-juice depending on their preference and ability. Many newbie vapers may not know this but e liquids vary not only in flavors, but on nicotine levels as well.
Each milliliter of e-liquid contains a dose of nicotine in milligrams. Some vapers still suffer from confusion—does nicotine in ml and percentage mean the same thing? Most of the time, e-liquid nicotine strengths are shown in mg/mL, which stands for milligrams per milliliter. This means that for every milliliter of e-liquid in the bottle, there is the specified amount of nicotine. Nicotine strengths shown in percentages are very similar, but a little easier to understand for many. Technically, this measurement is called “nicotine by volume,” in the same way the percentages on a bottle of liquor are “alcohol by volume” or ABV for short.
