micromole per liter to millimole per milliliter
Convert micromole per liter (μmol/L) to millimole per milliliter (mmol/mL). Use an editable molar concentration converter, conversion formula, and reference table.
1 μmol/L = 0.000001 mmol/mL
Conversion formula
One micromole per liter equals 0.000001 millimole per milliliter. Multiply your value in micromole per liter by this factor to get millimole per milliliter. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 micromole per liter:5 × 0.000001 = 0.000005 mmol/mL

About these measurements
Molar concentration is amount of substance per unit volume.
The base reference used here is the mole per cubic meter. One micromole per liter is 0.001 base units; one millimole per milliliter is 1,000 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 μmol/L to mmol/mL?
Multiply the quantity in μmol/L by 0.000001. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the millimole per milliliter to micromole per liter converter.
