WebThe candela per square metre (symbol: cd/m2) 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 2 ). [1] WebThe SI unitfor luminance is candela per square metre(cd/m2). A non-SI term for the same unit is the nit. The unit in the Centimetre–gram–second system of units (CGS)(which predated the SI system) is the stilb, which is equal to one candela per square centimetre or 10 kcd/m2.
