Quick answer
Molar concentration is amount of substance per unit volume. The SI unit is moles per cubic metre, but chemistry works in moles per litre: one mol/L is 1,000 mol/m³ and is spoken as 1 molar. Conveniently, one millimole per litre is exactly one mole per cubic metre.
| Mole per cubic metre (mol/m³) | 1 |
| Mole per litre (mol/L) | 0.001 |
| Millimole per litre (mmol/L) | 1 |
| Micromole per litre (µmol/L) | 1000 |
| Mole per cubic centimetre (mol/cm³) | 0.000001 |
About the Concentration - Molar Converter
Molar concentration, or molarity, measures the amount of a dissolved substance per unit of solution volume, typically moles per litre. The SI unit is the mole per cubic metre.
It is one of the most common ways to express concentration in chemistry.
Frequently Asked Questions
What is molarity?
⌄
Molarity is the number of moles of solute dissolved in one litre of solution.
How many mol/m³ are in 1 mol/L?
⌄
One mole per litre equals 1,000 moles per cubic metre.
Why is molar concentration used?
⌄
It directly links to the number of particles in solution, which governs reaction rates and chemical equilibrium.
