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.
