For the unit of information entropy, see [[Nat (information)]].'' The '''[[candela]] per [[square metre]]''' (cd/m²) is the [[SI]] [[unit of measurement|unit]] of [[luminance]]; '''nit''' is a non-SI name also used for this unit. It is often used to quote the brightness of [[computer display]]s, which typically have luminances of 50 to 300 nits (the [[sRGB]] spec for monitors targets 80 nits). Modern flat-panel (LCD and plasma) displays often exceed 300 cd/m² or 300 nits. "Nit" is believed to come from the Latin "nitere" = to shine. ==References== * IEC 61966-2-1:1999 is the official specification of sRGB. ==External links== * [http://www.optics.arizona.edu/Palmer/rpfaq/rpfaq.htm Radiometry vs. Photometry FAQ] ==See also== * [[Liquid crystal display]] * [[Light-emitting diode]] * [[Photometry (optics)]] {{SI light units}} [[Category:Units of luminance]] [[Category:Photometry]] [[Category:SI derived units]] [[be-x-old:Ніт]] [[bg:Кандела на квадратен метър]] [[de:Nit (Leuchtdichteeinheit)]] [[fr:Candela par mètre carré]] [[ko:칸델라 매 제곱미터]] [[it:Nit (unità di misura)]] [[nl:Nit]] [[ja:カンデラ毎平方メートル]] [[pl:Nit (jednostka)]] [[ru:Нит]]
