Why the estimate is credible
The site first converts AQI into an estimated PM2.5 concentration and then applies Berkeley Earth's cigarette-equivalence framing.
The estimate is most useful for comparing air-quality dose across times, situations, and repeated days. It should not be treated as a literal smoking-equivalence medical claim.
