About Microcandelas per square metre
The microcandela per square metre (µcd/m²) equals 10⁻⁶ cd/m². Used in precision dark-sky photometry and in measuring the luminance of unlit passive surfaces. OLED deep-black levels are typically 0.0001-0.01 cd/m², about 100-10 000 times larger than this scale. 1 µcd/m² = 10⁻⁶ cd/m².
About Stilbs
The stilb (sb) equals 1 cd/cm² = 10⁴ cd/m². The CGS luminance unit. A candle flame has luminance ~0.5-0.6 sb; a frosted incandescent bulb ~10 sb; a xenon short-arc lamp up to 170 000 sb. Named from the Greek στίλβω (to glitter). Found in pre-1970 photometry texts. 1 sb = 10⁴ cd/m².
