Micrograms per cubic meter of PM2.5 to cigarettes per day
Type a value in µg/m³ to get it in cigarettes instantly.
That's 2.4× as polluted as the WHO yearly guideline, while the WHO daily guideline is 1.25× more polluted. On the US index that is AQI 56: moderate.
Convert the other way: cigarettes to µg/m³
What it means
How dirty is that air?
For 24-hour averages of PM2.5 only. Official AQI values take the worst of several pollutants; hourly readings shown by apps are estimates.
The math
How to convert µg/m³ to cigarettes
To convert micrograms per cubic meter of PM2.5 to cigarettes per day, multiply by 0.0454545.
Example: 12 µg/m³ × 0.0454545 = 0.545455 cigarettes.
In the other direction, 1 cigarettes = 22 µg/m³.
