How to convert millimoles per liter to micromoles per liter
µmol/L = mmol/L × 1,000Multiply the value in millimoles per liter by 1,000. To go the other way, multiply by 0.001 (or divide by 1,000).
A millimole per liter is larger than a micromole per liter: one millimole per liter contains 1,000 micromoles per liter.

About the units
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).
Micromole per liter (µmol/L)
The micromole per liter (µmol/L) is a unit of molar concentration (molarity) in the International System of Units (SI). One micromole per liter equals 0.001 moles per cubic meter (mol/m³).
Frequently asked questions
How many micromoles per liter are in one millimole per liter?
There are 1,000 micromoles per liter in one millimole per liter, and this value is exact by definition.
How do I convert millimoles per liter to micromoles per liter?
Multiply the number of millimoles per liter by 1,000. For example, 10 mmol/L × 1,000 = 10,000 µmol/L.
How many millimoles per liter are in one micromole per liter?
One micromole per liter equals 0.001 millimoles per liter. That is the reverse factor, 1 ÷ 1,000.
What is 10 millimoles per liter in micromoles per liter?
10 mmol/L = 10,000 µmol/L.
Is this mmol/L to µmol/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.
