Spat (angular unit)

The spat (symbol sp), from the Latin spatium ("space"), is a unit of solid angle. One spat is equal to 4 $π$ steradians or approximately 41253 square degrees of solid angle (sequence A125560 in the OEIS). Thus 1 sp is the solid angle subtended by a complete sphere at its center.
