About Candelas per square foot
The candela per square foot (cd/ft²) equals 1/0.09290304 cd/m² ≈ 10.76 cd/m². Used in US lighting engineering; an illuminated office ceiling panel has luminance ~4-8 cd/ft². The ANSI ergonomic limit for computer workstation background sources is ~340 cd/ft². 1 cd/ft² = 1/0.09290304 cd/m².
About Nanocandelas per square metre
The nanocandela per square metre (ncd/m²) equals 10⁻⁹ cd/m². Represents luminance at the threshold of cooled photomultiplier tubes and avalanche photodiode detectors. The darkest OLED black levels (~10⁻⁴ cd/m²) are still five orders of magnitude brighter; this unit is used in single-photon counting photometry. 1 ncd/m² = 10⁻⁹ cd/m².
