An obsolete unit of luminous intensity in France, bougie" is a French word meaning "candle", the decimal candle, is defined as one twentieth of a Violle or equivelent to 1.0085 candela.
The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 1012 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian.
A former French unit of luminous intensity was defined as the intensity of a standard Carcel lamp. It is the horizontal intensity of a Carcel lamp (an Argand-type lamp with mechanical draft) burning 42 grams of colza oil per hour. One carcel equals approximately 9.61 international candles, or 0.98 candela.
Unit of luminous intensity, new equates 1 candela.
An obsolete unit of luminous intensity based on the light emitted from a candle made to a specified formula. Since 1948 the term candlepower was replaced by the international unit (SI) known as the candela. One old candlepower is about 0.981 candela. Less scientifically, modern candlepower now equates 1 candela.
Hefner candle, a fromer German unit of luminous intensity, defined by a flame standard, and equal to about nine-tenths of an international candle, or about 0.92 candela.
A fromer German unit of luminous intensity, defined by a flame standard, and equal to about nine-tenths of an international candle, or about 0.92 candela.
10 candle power, 10 candela of uminous intensity.
An old unit of luminous intensity. 1 violle is the luminous intensity of 1 cm² of platinum at its melting point of 1042 kelvin.
