Description
An obsolete unit for light intensity measurements based on the amount of light produced by one candle. The Standard International Candle is defined as the intensity of light emitted from a 1/6-pound spermaceti candle, burning at a rate of 120 grams per hour, duplicated in an incandescent lamp. 'Candle' has been replaced by candela for measurement of luminous intensity. One candle equals 1.02 candelas.
