Spat (angular unit)
Unit of angle in solid geometry From Wikipedia, the free encyclopedia
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 (sequence A125560 in the OEIS).[2] Thus it is the solid angle subtended by a complete sphere at its center.[2]

The whole sphere contains ~148.510 million square arcminutes and ~534.638 billion square arcseconds.
