About Picocandelas per square metre
The picocandela per square metre (pcd/m²) equals 10⁻¹² cd/m². A theoretical subunit for precision photometric standards and astrophysical brightness modelling. Even the darkest measurable surfaces in calibrated laboratories have luminance many orders of magnitude above this scale. Used only in radiometric standard traceability chains. 1 pcd/m² = 10⁻¹² cd/m².
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.
