Convert Picolumens to Nanolumens
Convert Picolumens (plm) to Nanolumens (nlm) instantly and accurately.
Conversion Formula
nlm = plm × 0.001
About Picolumens
The picolumen (plm) equals 10⁻¹² lm. A sub-unit used only in precision optical metrology and photomultiplier calibration chains. Equivalent to the photometric output of a 555 nm monochromatic source radiating approximately 1.46 fW of radiant power. Below the sensitivity threshold of most photometric instruments without special cooling. 1 plm = 10⁻¹² lm.
About Nanolumens
The nanolumen (nlm) equals 10⁻⁹ lm. The scale of single-cell bioluminescence: an individual bioluminescent bacterium emits roughly 1-100 nlm; a luciferin-luciferase reaction in a single cell reaches the low-nanolumen range. Also the range for fiber-optic evanescent-wave sensors and fluorescence microscopy background levels. 1 nlm = 10⁻⁹ lm.
