picolumen to nanolumen
Convert picolumen (plm) to nanolumen (nlm). Use an editable luminous flux converter, conversion formula, and reference table.
1 plm = 0.001 nlm
Conversion formula
One picolumen equals 0.001 nanolumen. Multiply your value in picolumen by this factor to get nanolumen. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 picolumen:5 × 0.001 = 0.005 nlm

About these measurements
Luminous flux measures the visible-light output weighted by human visual sensitivity.
The base reference used here is the lumen. One picolumen is 1e-12 base units; one nanolumen is 1e-9 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 plm to nlm?
