How to Convert PPB to Mols per Cubic Meter
Converting parts per billion (PPB) to mols per cubic meter (mol/m³) is a common conversion, especially for gases. Assuming ideal gas behavior at standard temperature and pressure (STP), 1 mole of any gas occupies 22.4 liters. Since 1 cubic meter equals 1000 liters, 1 mol/m³ is equivalent to 22.4 liters of gas per 1000 liters of volume, or 0.0224 volume fraction. To convert PPB to mol/m³, divide by 22,400,000,000.
Formula
Mols/m³ = PPB / 22,400,000,000
or
mol/m³ = PPB / 22,400,000,000
Step-by-step process
- Take the measurement in PPB
- Divide that number by 22,400,000,000
- The result is the equivalent amount in mols per cubic meter (volume/volume, for ideal gases at STP)
Examples
- 1 PPB = 0.00000000004464 mol/m³
- 1000 PPB = 0.00000004464 mol/m³
- 22,400,000,000 PPB = 1 mol/m³
When to Convert PPB to Mols per Cubic Meter
This conversion is frequently used in environmental science, air quality monitoring, and industrial hygiene to express the concentration of gaseous pollutants or other substances in the atmosphere, especially for very low concentrations.

Frequently Asked Questions
How many mols per cubic meter are in one PPB?
For ideal gases at STP, there are approximately 0.00000000004464 mols per cubic meter (volume/volume) in one PPB.
Why is the conversion factor 1/22,400,000,000?
At standard temperature and pressure (STP), 1 mole of any ideal gas occupies 22.4 liters. Since 1 cubic meter is 1000 liters, 1 mol/m³ is equivalent to 22.4 L/m³. To convert PPB to mol/m³, we divide by 1,000,000,000 and then multiply by 1000/22.4, which simplifies to dividing by 22,400,000,000.
