Unit Converter (ppm - ppb - µg/m³ - mg/m³ - vol.%)
In air quality monitoring, there are various units of measurement for the gases involved. For example, it's common to measure carbon dioxide concentration in ppm (parts per million). The amount of particulate matter, on the other hand, is usually given in µg/m³ — since particulate matter particles can vary in size. To make measurements from different sources comparable, they need to be converted into the same unit. Our unit converter helps with that.

Converting Units of Measurement for Gases
Whether you're an air quality expert or simply want to learn more about the air around you — our unit converter gives you a simple way to convert units. Temperature and air pressure are also taken into account. Below you'll find an overview of common units of measurement for the concentration of a gas or substance in the air.
ppm (Parts per Million): 1 ppm corresponds to 1 part per million parts of a gas.
ppb (Parts per Billion): 1 ppb corresponds to 1 part per billion parts of a gas.
mg/m³ (Milligrams per Cubic Meter): Indicates the mass of a substance per unit volume of air in mg/m³.
µg/m³ (Micrograms per Cubic Meter): Indicates the mass of a substance per unit volume of air in µg/m³.
