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 Largely superseded by cd/m² and foot-lamberts in modern display standards. 1 mL = 10/π cd/m².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 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.
