millilumen to microlumen
Convert millilumen (mlm) to microlumen (μlm). Use an editable luminous flux converter, conversion formula, and reference table.
1 mlm = 1,000 μlm
Conversion formula
One millilumen equals 1,000 microlumen. Multiply your value in millilumen by this factor to get microlumen. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 millilumen:5 × 1,000 = 5,000 μlm

About these measurements
Luminous flux measures the visible-light output weighted by human visual sensitivity.
The base reference used here is the lumen. One millilumen is 0.001 base units; one microlumen is 0.000001 base units.
Important distinctions
Lumens measure light output; lux measures illumination per unit area.
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 mlm to μlm?
Multiply the quantity in mlm 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 microlumen to millilumen converter.
