Why is it called 2.5?
The 2.5 in PM2.5 refers to the size of the pollutant in micrometers. Bear with us here while it gets a bit mathematics-y! Micrometers have this symbol: µm and are equivalent to 0.001 millimeters. The smallest thing that the average human eye can perceive is about 0.1 millimeters, which is around the same width as a human hair. So in order for us to see something as incredibly small as a micrometer, we need to use powerful microscopes.
