About Meganits

The meganit (Mcd/m²) equals 10⁶ cd/m². The scale for extreme light sources: outdoor LED video walls at peak brightness reach 3-10 Mcd/m²; laser exit apertures are typically 10-10 000 Mcd/m²; the solar disc at zenith has luminance ≈1 600 Mcd/m² (1.6×10⁹ cd/m²). Used in laser safety and high-power illumination. 1 Mcd/m² = 10⁶ cd/m².

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.
