💨 What Is an AQI to Cigarette Converter?

The AQI to Cigarette Exposure Converter is a unique health-awareness tool that helps you visualize air pollution exposure in a relatable way — by converting the Air Quality Index (AQI) or PM2.5 concentration into the number of cigarettes you would have to smoke to inhale an equivalent amount of fine particulate matter.

It’s not a scare tactic — it’s science-based awareness. The goal is to help people understand how serious polluted air can be for their lungs and long-term health.

📊 How the Calculator Works

The converter uses the U.S. EPA’s AQI formula and the Berkeley Earth research equivalence model, which estimates that:

🧠 1 cigarette ≈ 22 µg/m³·day of PM2.5 exposure

This means that breathing air with an average PM2.5 of 22 micrograms per cubic meter for one full day gives you roughly the same fine-particle intake as smoking one cigarette.

The calculator follows a 3-step logic:

1. Convert AQI → PM2.5:
   It uses official EPA breakpoint data to convert AQI values into PM2.5 concentrations.
   For example:

   • AQI 50 ≈ 12 µg/m³

   • AQI 150 ≈ 55 µg/m³

   • AQI 200 ≈ 150 µg/m³

2. Adjust for Exposure Time:
   The exposure period (hours) is divided by 24 to get the fraction of a day.
   Example: 12 hours = 0.5 day exposure.

3. Calculate Cigarette Equivalent:
   Using the formula:

   $$\text{Cigarettes} = \frac{(\text{PM2.5}) \times (\text{Exposure Fraction})}{22}$$

   So, if AQI = 160 → PM2.5 ≈ 75 µg/m³, and you’re exposed for 24 hours:

   $$\text{Cigarettes} = \frac{75 \times 1}{22} ≈ 3.4 \text{cigarettes per day}$$

That means breathing Delhi, Bangkok, or Beijing-level air (AQI ≈ 160) all day is roughly like smoking 3–4 cigarettes daily.

🌍 Why This Matters

Air pollution is now one of the world’s leading environmental health risks.
According to WHO, over 90% of people breathe air that exceeds safe PM2.5 limits.

By comparing air pollution exposure to cigarette smoking, the AQI → Cigarette Converter makes an abstract number (AQI) easier to understand.
It transforms “AQI 200” from just a number into something tangible:

“Breathing this air all day is like smoking 5 cigarettes.”

That insight encourages people to take precautions — use air purifiers, avoid outdoor workouts during high pollution, or wear N95 masks on smoggy days.

🧠 Important Notes

This calculator is for educational purposes only — it doesn’t mean you can replace cigarettes with polluted air!
Actual health effects depend on many factors:

• Individual lung sensitivity

• Particle composition

• Activity level (how much air you breathe per hour)

• Indoor air quality and filtration

Still, it provides a powerful visual metric to raise awareness about the invisible dangers of polluted air.
