decalumen to millilumen
Convert decalumen (dalm) to millilumen (mlm). Use an editable luminous flux converter, conversion formula, and reference table.
1 dalm = 10,000 mlm
Conversion formula
One decalumen equals 10,000 millilumen. Multiply your value in decalumen by this factor to get millilumen. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 decalumen:5 × 10,000 = 50,000 mlm

About these measurements
Luminous flux measures the visible-light output weighted by human visual sensitivity.
The base reference used here is the lumen. One decalumen is 10 base units; one millilumen is 0.001 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
