Ozone AQI: Using concentrations in milligrams or ppb?

20150906· First, ppm (parts per million ) and ppb (parts per billion) are defined as `1 ppm = 1/10 6 = 106 ` and `1 ppb = 1/10 9 = 109 `. So `1 ppm = 1000 ppb or 1 ppb = 103 ppm`. The conversion factor depends on the temperature at which you want the conversion (usually 25 degrees Centigrade in the US), as well as the ambient pressure. At an ambient ...
