About These Units
Hemisphere (hemisphere)
A hemisphere equals 2π steradians (≈6.283 sr)—half of a complete sphere. Represents the visible sky from any point on Earth, or one side of a surface. Used in lighting calculations: a horizontal surface receives radiation from a hemisphere of solid angle.
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.
