How to convert moles per liter to millimoles per liter
mmol/L = M × 1,000Multiply the value in moles per liter by 1,000. To go the other way, multiply by 0.001 (or divide by 1,000).
A mole per liter is larger than a millimole per liter: one mole per liter contains 1,000 millimoles per liter.
Worked examples
- 1 mole per liter (molar)1 M × 1,000 = 1,000 mmol/L
- 5 moles per liter5 M × 1,000 = 5,000 mmol/L
- 10 moles per liter10 M × 1,000 = 10,000 mmol/L
- 20 moles per liter20 M × 1,000 = 20,000 mmol/L
- 100 moles per liter100 M × 1,000 = 100,000 mmol/L

About the units
Mole per liter (M)
One mole of solute per litre of solution. One mole per liter equals 1,000 moles per cubic meter (mol/m³).
Millimole per liter (mmol/L)
The millimole per liter (mmol/L) is a unit of molar concentration (molarity) in the International System of Units (SI). One millimole per liter equals 1 mole per cubic meter (mol/m³).
Frequently asked questions
How many millimoles per liter are in one mole per liter?
There are 1,000 millimoles per liter in one mole per liter, and this value is exact by definition.
How do I convert moles per liter to millimoles per liter?
Multiply the number of moles per liter by 1,000. For example, 10 M × 1,000 = 10,000 mmol/L.
How many moles per liter are in one millimole per liter?
One millimole per liter equals 0.001 moles per liter. That is the reverse factor, 1 ÷ 1,000.
What is 10 moles per liter in millimoles per liter?
10 M = 10,000 mmol/L.
Is this M to mmol/L converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
