### CO2 Gas Concentration Defined |

When measuring gases like carbon dioxide, oxygen, or methane, the term concentration is used to describe the amount of gas by volume in the air. The 2 most common units of measurement are parts-per-million, and percent concentration. Parts-per-million (abbreviated ppm) is the ratio of one gas to another. For example, 1,000ppm of CO2 means that if you could count a million gas molecules, 1,000 ...

### How to Calculate PPM | Sciencing

2020-03-09· Going through a basic PPM calculation by volume or by mass will help to cement the concepts you need to understand. For mass, imagine you have liters of water with g of salt dissolved in it, noting that 1 L of water = 1 kg of mass, so the total mass in the example is 1 kg. After converting both to the same mass unit, the proportion of salt in the water is given by: So this is ...
