"WebCO2 monitors are a useful way to estimate airflow rates. The amount of CO2 in the air is measured in parts per million (ppm). 1000ppm is equivalent to about 10 litres per second, per person. CO2 levels consistently higher than 1500ppm in an occupied room indicate poor ventilation and you should take action to improve it. " - Ppm in the air

WebAug 20, 2024 · Ppm is often used for low concentration values, typical for air pollution. By definition, it is the number of gas particles per million air particles, 1 ppm = 1/1000000 = 0.0001% = 0.001‰. Sometimes, however, the gas concentration is expressed as the mass concentration in milligrams per cubic meter (mg/m3). WebPPM stands for parts of gas per million parts of air, and PPB is parts per billion. If that's not easy to imagine, try these examples: Part per million (ppm): 1 second in just under 2 weeks. 1 litre of water in a swimming pool. Part per billion (ppb): 1 second in 32 years. 1 ml of water in a swimming pool (that's about the size of a sugar cube).
