About Candelas per square inch
The candela per square inch (cd/in²) equals 1/0.00064516 cd/m² ≈ 1 550 cd/m². Used in US LED and CRT datasheets when citing luminance of small emitter areas. A high-brightness packaged LED chip in a focussed-beam configuration can reach 1-20 cd/in². 1 cd/in² = 1/(0.0254²) cd/m².
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.
