Complete guide to nicotine concentration: Use mg per ml to understand your e-cigarette nicotine strength (professional vape guide)
When choosing e-cigarette oil, you will always see numbers like 3mg, 10mg, 20mg or 0.6% or 2%. It sounds complicated but it’s actually very simple. This vape guide will use the most intuitive way to help you understand the relationship between nicotine strength and mg per ml, allowing you to quickly choose the right strength according to your own smoking habits and equipment, and no longer step into pitfalls.
1. First, let’s figure it out: What exactly do nicotine, nicotine strength and mg per ml refer to?
Nicotine is an alkaloid found in tobacco plants and is also found in trace amounts in tomatoes, potatoes, and eggplants. Traditional cigarettes burn nicotine, tar, and carbon monoxide to you, while e-cigarettes only dissolve nicotine in e-liquid and deliver it into the body through atomization.
In the field of electronic cigarettes, nicotine strength Generally marked in two ways:
- mg per ml（mg/mL） : How many mg of nicotine is contained in 1 ml of e-liquid, such as 10mg/mL
- Percent % : 1% = 10mg/mL, for example, 2% is 20mg/mL
All you need to remember is a simple conversion: mg/mL ÷ 10 = %，% × 10 = mg/mL . This is also the basic logic of all professional vape guides when talking about nicotine strength.

2. How to choose nicotine strength? According to “a few cigarettes per day + device mist volume”
Whether it is professional vape guides from Vaping360, Tablites or Vape Superstore, they all emphasize the same principle: When choosing nicotine strength, it depends on two things – how many cigarettes you smoke per day + whether you use small cigarettes or large cigarettes.
1. Recommended nicotine strength according to smoking amount
The following uses mg per ml as a benchmark to break down the common gears for you:
2. Let’s look at the fog volume of the equipment: how to match nicotine strength with low fog/medium fog/large fog
It is also 10mg/mL, but the body feeling is completely different when used on small cigarettes and high-power devices. Professional vape guides usually divide equipment into three categories according to the amount of vapor:
- Low fog volume : Small cigarette, closed reloading, compact MTL smoking
- medium fog volume : MTL with large ventilation or mild direct lung, small volume sub-ohm
- High fog volume : High-power sub-ohm atomizer, RTA/RDA, large smoke method
Low mist volume equipment is suitable for nicotine strength intensity range:
Recommended range: nicotine salt 20–60mg/mL (common in overseas markets), free base 12–24mg/mL
Medium mist volume equipment is suitable for nicotine strength intensity range:
Recommended range: 6–12mg/mL, Ni salt is about 10–20mg/mL
High mist volume equipment is suitable for nicotine strength intensity range:
Recommended range: 1.5–6mg/mL, usually no high nitrate salt is used
Simply put: The greater the fog, the lower the nicotine strength will be . Otherwise, you can easily inhale excessive nicotine in a short period of time, causing dizziness, nausea and other discomforts.
3. Free nicotine vs nicotine salt: same mg per ml, completely different experience
The same nicotine strength of 20mg/mL is used, and the throat feeling is much different if free nicotine (freebase) or nicotine salt (nic salt) is used.
