millimole per liter to micromole per liter
Convert millimole per liter (mmol/L) to micromole per liter (μmol/L). Use an editable molar concentration converter, conversion formula, and reference table.
1 mmol/L = 1,000 μmol/L
Conversion formula
One millimole per liter equals 1,000 micromole per liter. Multiply your value in millimole per liter by this factor to get micromole per liter. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 millimole per liter:5 × 1,000 = 5,000 μmol/L

About these measurements
Molar concentration is amount of substance per unit volume.
The base reference used here is the mole per cubic meter. One millimole per liter is 1 base units; one micromole per liter is 0.001 base units.
Important distinctions
Compound units must match the quantity and dimension. Temperature intervals use size factors rather than temperature offsets. Calorie and BTU entries use the explicit definitions shown.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert mmol/L to μmol/L?
Multiply the quantity in mmol/L by 1,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the micromole per liter to millimole per liter converter.
