About Millilamberts
The millilambert (mL) equals 10/π cd/m² ≈ 3.183 cd/m². Historically used in the United States to specify projection screen luminance and oscilloscope phosphor brightness. A projection screen with luminance 1 mL ≈ 3.18 cd/m². Largely superseded by cd/m² and foot-lamberts in modern display standards. 1 mL = 10/π cd/m².
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.
