Stilb (unit) meter. The current national standard for SI in the United States discourages the use of the stilb. formula_1 formula_2 formula_3 formula_4 formula_5 Other units of luminance: Stilb (unit) The stilb (sb) is the CGS unit of luminance for objects that are not self-luminous. It is equal to one candela per square centimeter or 10 nits (candelas per square meter). 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
Transverse measure Transverse measure In mathematics, a measure on a real vector space is said to be transverse to a given set if it assigns measure zero to every translate of that set, while assigning finite and positive (i.e. non-zero) measure to some compact set. Let "V" be a real vector space together with a metric space structure with respect to which it is a complete space. A Borel measure "μ" is said to be transverse to a Borel-measurable subset "S" of "V" if The first requirement ensures that, for example, the trivial measure is not considered to be a transverse measure.
