Stilb (unit)
The stilb is the CGS unit of luminance for objects that are not self-luminous. It is equal to one candela per square centimeter or 104 nits. The name was coined by the French physicist André Blondel around 1920. It comes from the Greek word stilbein, meaning 'to glitter'.
It was in common use in Europe up to World War I. In North America self-explanatory terms such as candle per square inch and candle per square meter were more common. The unit has since largely been replaced by the SI unit: candela per square meter. The current national standard for SI in the United States discourages the use of the stilb.;Candela:
