AQI to Cigarettes

AQI to Cigarettes Calculator

Complete conversion table showing cigarette equivalents for every AQI level from 1 to 500. Based on Berkeley Earth research formula.

๐Ÿ“Š How to Read

Find your AQI value to see how many cigarettes you're "smoking" per day by breathing that air.

๐Ÿงฎ Formula

PM2.5 = AQI converted using EPA breakpoints
Cigarettes = PM2.5 รท 22 (Berkeley Earth)

โš ๏ธ Health Note

Lower AQI = Better health. Aim for AQI under 50 for minimal health impact.

AQI to Cigarettes Conversion Chart

Visual representation of cigarette equivalents across AQI levels 0-500. Each point shows the equivalent cigarettes per day based on PM2.5 concentration.

AQI 50
โ‰ˆ 0.5 cigarettes/day
Good air quality
AQI 100
โ‰ˆ 1.6 cigarettes/day
Moderate pollution
AQI 200
โ‰ˆ 6.8 cigarettes/day
Unhealthy level
AQI 500
โ‰ˆ 22.7 cigarettes/day
Hazardous level

๐Ÿ“Conversion Formula

Step 1: Convert AQI to PM2.5 using EPA breakpoints

Step 2: Divide PM2.5 by 22 (Berkeley Earth research)

Result: Cigarettes per day equivalent
