How to Convert Molar Concentration Units
Molar concentration (molarity) is the amount of solute per unit volume of solution. The SI unit is mole per cubic metre (mol/m³); laboratories mostly use mol/L (M) and mmol/L.
Every unit on this page is stored as a fixed factor relative to one reference unit, the mole per cubic metre (mol/m³). Converting is a two step multiply and divide:
- Multiply your value by the factor of the source unit to get the value in mol/m³.
- Divide that result by the factor of the target unit.

Frequently Asked Questions
What is the SI unit of molar concentration?
The SI unit of molar concentration is the mole per cubic metre (mol/m³). Molar concentration (molarity) is the amount of solute per unit volume of solution.
How do I convert mol/L to mmol/L?
To convert mole per litre (molar) (mol/L) to millimole per litre (mmol/L), multiply the value in mol/L by 1,000. For example, 1 mol/L = 1,000 mmol/L.
How do I convert mmol/L to µmol/L?
To convert millimole per litre (mmol/L) to micromole per litre (µmol/L), multiply the value in mmol/L by 1,000. For example, 1 mmol/L = 1,000 µmol/L.
How do I convert mol/L to mol/m³?
To convert mole per litre (molar) (mol/L) to mole per cubic metre (mol/m³), multiply the value in mol/L by 1,000. For example, 1 mol/L = 1,000 mol/m³.
