You can do the reverse unit conversion from gigameters to light-day, or enter any two units below:
A light day (also written light-day) is a unit of length. It is defined as the distance light travels in an absolute vacuum in one day (of 86,400 seconds) or 25,902,068,371,200 metres (~26 Tm).
Note that this value is exact, since the metre is actually defined in terms of the speed of light. The light day isn't very frequently used at all since there are few astronomical objects or distances of that magnitude; the Oort cloud, for example, is thought to extend between 290 and 580 light-days out from the Sun.
A gigametre (American spelling: gigameter, symbol: Gm) is a unit of length equal to 10^9 metres. Its customary equivalent is 621,371 miles.
