The pouce is a French "inch" unit. The modern definition from the international standard of units is that 1 inch = 2.54 cm or 1 pouce = 25.4 mm. The word pouce means "thumb" in French. In past history, it was equal to 1/12 pied. Based on the pied de roi, the historical pouce was equal to about 1.066 inches or 2.707 centimeters.

Definition: Light-day

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.
