The SI prefix "giga" represents a factor of 109, or in exponential notation, 1E9.
So 1 gigacandela = 109 candelas.
The definition of a candela is as follows:
The candela (symbol: cd) is the SI base unit of luminous intensity. It is the power emitted by a light source in a particular direction, weighted by the luminosity function. A common candle emits light with a luminous intensity of roughly one candela. The candela is officially defined as the luminous intensity of a source that emits monochromatic radiation of frequency 540×1012 hertz and that has a radiant intensity of 1/683 watt per steradian.
The SI prefix "pico" represents a factor of 10-12, or in exponential notation, 1E-12.
So 1 picocandela = 10-12 candelas.
