Micrograms per Cubic Metre / Parts per Billion ConverterAdmin2022-04-01T09:11:15+02:00 Micrograms per Cubic Metre (μg/m3) / Parts per Billion (PPB) Converter and Milligrams per Cubic Metre (mg/m3) / Parts per Million (PPM) Converter

The following calculators allow for the conversion of concentrations for a variety of pollutants between micrograms per cubic metre (µgm-3) and parts per billion (ppb), and between milligrams per cubic metre (mgm-3) and parts per million (ppm). A concentration in ppb (by volume) is the volume of a gaseous compound per billion volumes of ambient air whereas a concentration in µgm-3 is the mass of a gaseous compound (in µg) per cubic metre of ambient air.

This tool allows the user to convert between ambient concentration units at measurement temperatures (to a reference temperature of 0 degrees Celsius). It is particularly useful for standardising measurements taken for environmental studies.

We have created YouTube videos explaining the theory of the tool as well as a short clip demonstrating how the tool works. Click on the links below to watch our videos, subscribe to our channel and turn on post notifications to never miss an update!
