Choosing the right nicotine strength is one of the most important decisions for any vape user. It affects throat hit, satisfaction, and even how effective vaping can be as an alternative to smoking.

In this guide, we’ll break down nicotine strength in simple terms, compare percentage vs. mg/ml, review global regulations, and share insights from our R&D team and real users to help you make the best choice.

🔬 What Is Nicotine Strength?

Nicotine strength refers to the concentration of nicotine in e-liquid, expressed as a percentage (%) or milligrams per milliliter (mg/mL).

• 1% ≈ 10mg/ml

• 2% ≈ 20mg/ml

• 5% ≈ 50mg/ml

The higher the concentration, the stronger the throat hit and the faster the nicotine absorption.

📏 Percentage vs. mg/ml — What’s the Difference?

Both % and mg/ml describe the same thing, but in different units:

• %: grams of nicotine per 100ml of e-liquid

• mg/ml: milligrams of nicotine in each milliliter

For example:

• 2% = 20mg/ml

• 5% = 50mg/ml

👥 Why Nicotine Strength Matters for You

The right strength depends on smoking history and lifestyle:
