About AQI to Cigarettes Calculator
Our Mission
Air pollution is often invisible, making it difficult for people to understand its real impact on health. We created the AQI to Cigarettes Calculator to translate abstract air quality numbers into something everyone can instantly understand: the equivalent number of cigarettes smoked.
Our goal is simple: help people make informed decisions about their health by providing a clear, science-based way to visualize air pollution exposure.
How We Started
The idea for this calculator emerged from a simple observation: people understand the dangers of smoking, but air pollution remains an abstract concept despite being equally harmful. When wildfires blanketed major cities in smoke and AQI readings soared into the hundreds, news headlines would report numbers like "AQI 250" - but what does that actually mean for your health?
The breakthrough came when we discovered Berkeley Earth's research equating PM2.5 exposure to cigarette smoke. Suddenly, there was a way to make air pollution tangible. An AQI of 250 isn't just a number - it's like smoking a pack of cigarettes just by breathing the air for a day. That realization was startling and motivated us to create a tool that could help everyone understand their exposure.
We launched this calculator to bridge the gap between scientific data and public understanding. Air quality should be as easy to comprehend as a weather forecast.
The Science Behind It
Our calculator is based on peer-reviewed research from Berkeley Earth, a respected scientific organization focused on environmental data analysis. Their groundbreaking study established that breathing air with a PM2.5 concentration of 22 µg/m³ for 24 hours is roughly equivalent to smoking one cigarette.
This research allows us to convert Air Quality Index (AQI) values into cigarette equivalents, making the invisible threat of air pollution tangible and understandable.
Our Calculation Method
- Convert AQI to PM2.5: We use the EPA's standard conversion formula to translate AQI values into PM2.5 concentrations
- Apply the Berkeley Earth Formula: We calculate cigarette equivalents based on your exposure time and the PM2.5 level
- Provide Context: We help you understand what your result means for your health
Why This Matters
According to the World Health Organization:
- 99% of the global population breathes air that exceeds WHO guideline limits
- Air pollution causes an estimated 7 million premature deaths annually
- Both outdoor and indoor air pollution contribute to health problems
By making air pollution's impact more relatable, we hope to:
- Raise awareness about air quality issues
- Encourage people to check local AQI before outdoor activities
- Support better decision-making for sensitive groups (children, elderly, those with respiratory conditions)
- Advocate for cleaner air policies
The Personal Impact
Air pollution isn't just a distant environmental problem - it affects you right now. Whether you're:
- A parent deciding whether your child can play outside today
- An athlete planning your morning run route
- Someone with asthma managing daily triggers
- A commuter wondering if you should bike or take transit
- Anyone breathing in a city with variable air quality
Understanding your air pollution exposure in concrete terms empowers you to make informed choices. When you see that breathing today's air is equivalent to smoking 3 cigarettes, the decision to move your workout indoors becomes clear.
Who We Are
We're a team of developers, environmental scientists, and health advocates who believe that public health information should be accessible, accurate, and actionable. Our backgrounds span software engineering, environmental science, public health communication, and data visualization.
What unites us is a commitment to making complex environmental data understandable. We've seen too many people ignore air quality warnings because the numbers felt abstract. By translating AQI into a universally understood comparison, we're helping millions make better health decisions daily.
This project is maintained by volunteers passionate about air quality and public health. We continuously update our data sources, improve our calculator accuracy, and expand our educational resources based on the latest scientific research.
Data Sources
We rely on trusted, authoritative sources for our calculations and information:
- U.S. Environmental Protection Agency (EPA) - AQI standards and PM2.5 conversion formulas
- Berkeley Earth - Research on PM2.5 and cigarette smoke equivalency
- World Health Organization (WHO) - Global air quality guidelines and health impact data
Our Commitment to Accuracy
Scientific understanding of air pollution evolves constantly. We stay current by:
- Monitoring peer-reviewed research on air quality and health impacts
- Updating our algorithms when new conversion standards are published
- Verifying our calculations against established medical and environmental databases
- Transparently documenting our methodology so users understand exactly how results are derived
If you notice any discrepancies or have questions about our methods, we encourage you to reach out. Accuracy is paramount when dealing with health information.
Our Impact
Since launch, our calculator has been used millions of times by people around the world:
- Parents protecting their children during wildfire season
- Athletes optimizing training schedules based on air quality
- Healthcare providers educating patients about environmental health risks
- Policymakers communicating the urgency of air quality improvements
- Journalists making pollution stories more relatable to readers
We've received countless messages from users saying the cigarette comparison finally made air pollution "click" for them. One user wrote: "I've ignored AQI for years, but seeing that yesterday's air was like smoking 8 cigarettes made me buy an air purifier that day."
That's the impact we're working toward - turning awareness into action.

Looking Forward
Air pollution is one of the most pressing public health challenges of our time, but it's also solvable. As more people understand their exposure and demand action, we move closer to cleaner air for everyone.
Our Future Goals
- Expand global coverage with local AQI data integration
- Develop mobile apps for on-the-go air quality checking
- Create educational partnerships with schools and health organizations
- Launch community features allowing users to share local air quality observations
- Advocate for policy change using data to demonstrate the health burden of air pollution
We're just getting started. Clean air is a human right, and we're committed to using technology and clear communication to help achieve it.

This calculator is designed for educational purposes to help visualize air pollution's potential health impact. It should not be used as medical advice. For health concerns related to air quality, please consult healthcare professionals.
The cigarette equivalency is a simplified comparison to help communicate risk and does not suggest that air pollution and smoking have identical health effects. Both pose serious health risks that should be minimized whenever possible.
