Spat (unit)
From Infogalactic: the planetary knowledge core
The spat (symbol sp[1]), from the Latin spatium ("space"), is a unit of solid angle.[2][3] 1 spat is equal to 4π steradians[1][3] or approximately 41253 square degrees of solid angle.[2] As such, it is the solid angle of a sphere.[2]
The spat (symbol S[4]) is also an obsolete unit of distance used in astronomy.[4][2] It is equal to one 1000000000 kilometres (1 Tm or 1012 m).[4][2] It is about 6.6846 astronomical units (AUs),[2] 1.057×10−4 light-years or 3.240×10−5 parsecs.
