How is this AQI calculated?

The primary Air Quality Index (AQI) shown above is calculated using the US EPA Linear Interpolation formula based on PM2.5 concentration (Fine Particulate Matter).

Formula: Ip = [(Ihi - Ilow) / (Chi - Clow)] * (Cp - Clow) + Ilow

Current PM2.5: 4.5 µg/m³
Calculation: Your city falls into the "Good" category (Category 1).
