Introduction: Understanding Nicotine Strength
Understanding nicotine strength helps you read e-liquid and pod vape labels more accurately. When comparing nicotine vapes, you may see concentrations listed as 5 mg/mL, 20 mg/mL, 2%, or 0.6%. Although these labels look different, mg/mL and percentage can represent the same nicotine concentration.
Milligrams per millilitre (mg/mL) indicates how much nicotine is present in each millilitre of e-liquid, while percentage expresses concentration in another format. This guide explains vape nicotine levels and how to interpret labels without confusing concentration with total nicotine content.
Using the common conversion, 1% equals 10 mg/mL. Therefore, 20 mg/mL equals 2%, 6 mg/mL equals 0.6%, and 5 mg/mL equals 0.5%, not 5%.
What Is Nicotine Strength?
Nicotine strength describes the concentration of nicotine in a vaping liquid. It is commonly shown in Canada as milligrams per millilitre, or mg/mL, although you may also see a percentage.
A higher concentration means more nicotine is present in a given amount of liquid. It does not, by itself, tell you exactly how much nicotine your body absorbs from each puff.
For Canadian adults comparing nicotine vapes, understanding the label helps distinguish nicotine concentration from total nicotine content. Labels describe the concentration of nicotine in vapes, not necessarily the amount absorbed during use.
What Does mg/mL Mean?
mg/mL means milligrams of nicotine per millilitre of e-liquid. Understanding vape nicotine levels starts with reading this measurement correctly.
For example:
-
5 mg/mL = 5 milligrams of nicotine in every 1 mL of liquid.
-
10 mg/mL = 10 milligrams per 1 mL.
-
20 mg/mL = 20 milligrams per 1 mL.
This is a concentration measurement, not the total amount in the bottle.
A 30 mL bottle labelled 20 mg/mL contains more total nicotine than a 10 mL bottle labelled 20 mg/mL because the larger bottle contains more liquid.
What Does Nicotine Percentage Mean?
Nicotine can also be expressed as a percentage. When comparing nicotine levels in vape products, it is important to understand how this measurement relates to mg/mL.
For common vape-liquid labels, the useful rule of thumb is:
Percentage = mg/mL ÷ 10
So:
-
20 mg/mL = 2%
-
10 mg/mL = 1%
-
6 mg/mL = 0.6%
-
5 mg/mL = 0.5%
-
3 mg/mL = 0.3%
That is why a 20 mg nicotine vape and a 2% nicotine vape can describe the same nicotine concentration.
mg/mL vs Percentage: Are They the Same?
They can represent the same concentration, just in different formats.
| Label | Equivalent concentration | What it means |
|---|---|---|
| 3 mg/mL | 0.3% | 3 mg nicotine per mL |
| 5 mg/mL | 0.5% | 5 mg nicotine per mL |
| 6 mg/mL | 0.6% | 6 mg nicotine per mL |
| 10 mg/mL | 1% | 10 mg nicotine per mL |
| 20 mg/mL | 2% | 20 mg nicotine per mL |
Compare like with like mg/mL is a concentration measurement, while % expresses that concentration another way.
How to Convert mg/mL to Percentage
The simple conversion is:
mg/mL ÷ 10 = percentage
For example:
20 ÷ 10 = 2%
And in reverse:
0.6% × 10 = 6 mg/mL
The same method works across product categories that use different labelling styles.
Nicotine Strength Conversion Chart
The following chart helps you compare common vape nicotine levels using the standard conversion of 1% = 10 mg/mL.
| Nicotine strength | Percentage equivalent |
|---|---|
| 0 mg/mL | 0% |
| 3 mg/mL | 0.3% |
| 5 mg/mL | 0.5% |
| 6 mg/mL | 0.6% |
| 10 mg/mL | 1% |
| 15 mg/mL | 1.5% |
| 20 mg/mL | 2% |
For Canadian vaping products, 20 mg/mL is the federal maximum nicotine concentration. According to Health Canada’s Vaping Product Safety guidance, legal vaping products have a maximum nicotine concentration of 20 mg/mL, and product labels must display nicotine concentration in mg/mL.
Is 5 mg the Same as 5%?
No.
This is one of the most common nicotine-label mistakes. A common error when reading nicotine levels in vape products is confusing milligrams per millilitre with percentages.
If a product is labelled 5 mg/mL, that is equivalent to 0.5% using the standard conversion.
By contrast, 5% corresponds to 50 mg/mL, which is higher than the 20 mg/mL federal maximum for vaping products covered by Canada's regulations.
A quick memory trick:
Divide mg/mL by 10 to convert it to a percentage.
So 20 mg/mL becomes 2%, while 5 mg/mL becomes 0.5%.
What Does 20 mg/mL or 2% Mean in Canada?
In Canada, 20 mg/mL is equivalent to approximately 2% nicotine using the common conversion for vape liquids, where 1% equals 10 mg/mL.
According to Health Canada’s vaping product regulations, the federal Nicotine Concentration in Vaping Products Regulations establish a maximum nicotine concentration of 20 mg/mL for vaping products manufactured or imported for sale in Canada. These regulations came into force on July 8, 2021.
A label showing 20 mg/mL indicates the concentration of nicotine in the e-liquid, not the amount your body absorbs. Canadian labelling requirements specify that nicotine concentration must be displayed in mg/mL. Percentage values can help consumers understand the equivalent concentration, but they should not replace checking the product’s labelled nicotine strength.

Nicotine Strength vs Total Nicotine Content
These terms are easy to mix up.
Nicotine strength tells you the concentration per millilitre.
Total nicotine content depends on both concentration and the volume of liquid. When calculating the total amount of nicotine in vapes, you need to consider both measurements.
For example, a 30 mL bottle labelled 20 mg/mL contains:
20 mg × 30 mL = 600 mg of nicotine in the liquid.
That does not mean your body will absorb 600 mg. Actual delivery depends on how the product is used and other factors.
Does Nicotine Strength Tell You How Much You Absorb?
No. Nicotine concentration is only one part of nicotine delivery.
Actual exposure can vary with the device, power output, coil and aerosol production, puff duration, frequency of use, and nicotine formulation.
Nicotine formulation can matter too. Controlled research has found differences in nicotine delivery and subjective effects between salt and freebase formulations.The nicotine levels in vape labels show concentration, not the precise amount absorbed by the user.
That is why you should not assume that two products with the same labelled strength will necessarily feel identical.
Nicotine Salts vs Freebase Nicotine
Nicotine salts and freebase nicotine are two common forms of nicotine found in e-liquids. While both provide nicotine, their formulations and typical product formats can differ.
Nicotine salts are formulated with an acid, creating a weakly acidic mixture, and are commonly associated with pod-style vaping products. The nicotine strength can be listed in mg/mL or percentage, so checking the label is important when comparing products. Device type, labelled nicotine concentration, and intended usage should also be considered rather than relying on nicotine percentage alone.
Key Points:
-
Pod-style vaping
-
Different nicotine strengths
-
mg/mL or percentage
-

When comparing the two, look at the nicotine concentration, nicotine form, device type, e-liquid volume, and product specifications rather than focusing on the percentage alone.
VapeItOff.ca carries both freebase e-liquids and salt-based e-liquids, so the strength label is useful when comparing the two.
How Device Type Can Affect Nicotine Delivery
The same nicotine concentration can behave differently across devices.
A lower-powered pod and a higher-powered device can produce different amounts of aerosol from each puff. Your puff style and how frequently you vape also matter.
The labelled vape nicotine levels are only one part of the overall picture. When comparing products, consider:
-
Nicotine concentration: mg/mL or percentage.
-
Nicotine form: freebase or salt.
-
Device type: pod, disposable, tank, or other system.
-
Usage pattern: puff frequency and duration.
-
E-liquid volume: important for calculating total nicotine in the liquid.
The label is only the starting point.
Common Nicotine Label Mistakes
Before choosing a product, watch for these common mix-ups:
-
Confusing 5 mg/mL with 5%: they are not equivalent.
-
Treating concentration as total content: 20 mg/mL does not mean 20 mg total in the bottle.
-
Assuming strength equals absorption: delivery also depends on the product and how it is used.
-
Forgetting Canadian limits: products sold in Canada are subject to the federal 20 mg/mL maximum.
Conclusion: Understand the Label Before You Choose
Understanding vape nicotine levels becomes easier once you know the difference between mg/mL and percentage. The key conversion to remember is simple: 1% equals 10 mg/mL. That means 20 mg/mL is 2%, 6 mg/mL is 0.6%, and 5 mg/mL is 0.5%.
Remember that nicotine concentration is only one factor when comparing vaping products. Bottle size, nicotine type, device, and usage all affect the overall experience and nicotine delivery. The concentration label also does not tell you exactly how much nicotine in vapes your body absorbs.
