Candela per square metre (cd/m²), commonly referred to as "nits," is a unit of measurement for luminance. It quantifies the amount of light that is emitted from a surface in a particular direction. Specifically, one candela per square metre is equivalent to one candela (the SI unit of luminous intensity) spread uniformly over a square meter of area.
