How to Convert PPM to Mols per Liter
Converting parts per million (PPM) to mols per liter (mol/L) is a common conversion. Assuming ideal gas behavior at standard temperature and pressure (STP), 1 mole of any gas occupies 22.4 liters. Since 1 liter is 0.001 cubic meters, 1 mol/L is equivalent to 1000 mol/m³. To convert PPM to mol/L, you divide by 22,400,000.
Formula
Mols/L = PPM / 22,400,000
or
mol/L = PPM / 22,400,000
Step-by-step process
- Take the measurement in PPM
- Divide that number by 22,400,000
- The result is the equivalent amount in mols per liter (volume/volume, for ideal gases at STP)
Examples
- 1 PPM = 0.00000004464 mol/L
- 1000 PPM = 0.00004464 mol/L
- 22,400,000 PPM = 1 mol/L
When to Convert PPM to Mols per Liter
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.

Frequently Asked Questions
How many mols per liter are in one PPM?
For ideal gases at STP, there are approximately 0.00000004464 mols per liter (volume/volume) in one PPM.
Why is the conversion factor 1/22,400,000?
At standard temperature and pressure (STP), 1 mole of any ideal gas occupies 22.4 liters. Since 1 liter is 0.001 cubic meters, 1 mol/L is equivalent to 1000 mol/m³. To convert PPM to mol/L, we divide by 1,000,000 and then multiply by 1/1000, which simplifies to dividing by 22,400,000.
