Molar Concentration Converter — mol/L, mmol/L, μmol/L
Convert between 6 units of molar concentration — mol/L (M), mmol/L (mM), μmol/L (μM), nmol/L (nM), pmol/L (pM), and kmol/m³. Molar concentration expresses moles of solute per litre of solution. Blood glucose of 5 mmol/L is normal; seawater contains ~600 mmol/L NaCl. Essential in pharmaceutical dosing, clinical diagnostics and chemical reaction calculations.

About the Molar Concentration Converter
Molar concentration (molarity, M) expresses the amount of a substance dissolved per litre of solution. It is the standard unit in chemistry, biochemistry, and medicine. Physiological saline is 0.9% NaCl — approximately 154 mM. Blood glucose is typically 4–6 mM. Drug dosages, reaction rates, and equilibrium constants all depend on molar concentrations.
Quick facts
- ›Blood glucose of 5 mM means 5 millimoles of glucose per litre of blood
- ›Seawater contains approximately 600 mM NaCl (about 35 g/L)
- ›Avogadro's number (6.022 × 10²³) defines how many particles are in one mole
- ›1 M (molar) = 1 mol/L = 1,000 mmol/L = 1,000,000 μmol/L
