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]
