lumen to centilumen
Convert lumen (lm) to centilumen (clm). Use an editable luminous flux converter, conversion formula, and reference table.
1 lm = 100 clm
Conversion formula
One lumen equals 100 centilumen. Multiply your value in lumen by this factor to get centilumen. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 lumen:5 × 100 = 500 clm

About these measurements
Luminous flux measures the visible-light output weighted by human visual sensitivity.
The base reference used here is the lumen. One lumen is 1 base units; one centilumen is 0.01 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 lm to clm?
