About These Units
Spat (sp)
The spat equals 4π steradians (≈12.566 sr)—the solid angle subtended by a complete sphere as seen from its center. One spat = 41,253 square degrees = 1 full sphere. Used in radiation physics and isotropic source calculations. Rarely used; steradians preferred.
Square Arcminute (arcmin²)
A square arcminute equals (1/60)² of a square degree or about 8.46×10⁻⁸ steradians. One square degree = 3,600 square arcminutes. Used for small astronomical fields: nebula sizes, galaxy images, and detector pixel scales. Full Moon ≈ 720 arcmin².
