Convert Microlumens to Picolumens
Convert Microlumens (µlm) to Picolumens (plm) instantly and accurately.
Conversion Formula
plm = µlm × 1000000
About Microlumens
The microlumen (µlm) equals 10⁻⁶ lm. LED indicators in deep-sleep power-save mode, fiber-optic signal pilots, and OLED display pixels at minimum brightness fall into this range. Equivalent to a 555 nm source radiating approximately 1.46 nW of radiant power. A night-vision display backlight operates at 1-100 µlm. 1 µlm = 10⁻⁶ lm.
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.
