How to Convert Mols per Liter to PPM
Converting mols per liter (mol/L) to parts per million (PPM) 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 mol/L to PPM, you multiply by 22,400,000.
Formula
PPM = Mols/L × 22,400,000
or
PPM = mol/L × 22,400,000
Step-by-step process
- Take the measurement in mols per liter
- Multiply that number by 22,400,000
- The result is the equivalent amount in PPM (volume/volume, for ideal gases at STP)
Examples
- 1 mol/L = 22,400,000 PPM
- 0.00000004464 mol/L = 1 PPM
- 0.001 mol/L = 22,400 PPM
When to Convert Mols per Liter to PPM
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 PPM are in one mol/L?
For ideal gases at STP, there are 22,400,000 PPM (volume/volume) in one mol/L.
Why is the conversion factor 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 mol/L to PPM, we multiply by 1,000 and then by 1,000,000/22.4, which simplifies to multiplying by 22,400,000.
