E-Cig Catridge to Stick per Day Calculator

This tool estimates the total nicotine (mg) in a single vape cartridge, converts it to the approximate number of cigarette sticks, and calculates sticks per day based on how long one cartridge lasts.

Enter Nicotine Strength (%) — e.g., 2.0

Enter Cartridge Volume (mL) — e.g., 1.5

Enter Days per Cartridge — e.g., 3

Simple dosage math:

Convert % to mg/mL: 1% nicotine = 10 mg/mL

Total nicotine per cartridge: mg/cartridge = mg/mL × volume (mL)

Daily nicotine: mg/day = mg/cartridge ÷ days per cartridge

Cigarette equivalents (assumption): 1 cigarette ≈ 1 mg nicotine absorbed

The 1 mg per cigarette value is a commonly used clinical average. Actual absorption can vary with device power, e-liquid composition, puff duration, and individual behavior.

Given:

• Nicotine strength = 2.0%
• Cartridge volume = 1.5 mL
• Days per cartridge = 3

Then:

• mg/mL = 2.0 × 10 = 20 mg/mL
• mg/cartridge = 20 × 1.5 = 30 mg
• mg/day = 30 ÷ 3 = 10 mg
• ≈ 10 cigarettes per day

Use this tool to understand nicotine per cartridge, estimate daily intake, and compare vaping to cigarettes. Helpful for self-monitoring, harm-reduction, or as part of a quit plan.
