About Candelas per square metre
The candela per square metre (cd/m²), informally called the nit, is the SI coherent unit of luminance. A typical laptop screen is 250-500 cd/m²; an HDR TV reaches 1 000-4 000 cd/m²; a clear blue sky is ~3 000-8 000 cd/m². Luminance is the photometric quantity directly perceived as brightness. 1 cd/m² = 1 nit.
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.
