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 'Candle' has been replaced by Candela for measurement of luminous intensity.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.
