The candela per square metre (symbol: cd/m ) is the unit of luminance in the International System of Units (SI). The unit is based on the candela, the SI unit of luminous intensity, and the square metre, the SI unit of area. The nit (symbol: nt) is a non-SI name also used for this unit (1 nt = 1 cd/m ). The term nit is believed to come from the Latin word nitēre, "to shine".
