A solid angle (symbol: Ω) the SI base unit is steradian or square radian.
A square degree unit is a non-SI unit measure of a solid angle. 1 deg2 is equal to 3.04617×10−4 sr.
A hemisphere unit has 2π steradians. The complete sphere has a solid angle of 4π steradians.
Multiply the hemispheres value by 20626.321318
square degree = hemispheres x 20626.321318
Divide the square degree value by 20626.321318
hemispheres = square degree / 20626.321318
One square degree (deg²) is equal to 0.000048 hemispheres
1 square degree (deg²) = 0.000048 hemispheres
One hemispheres is equal to 20626.321318 square degree (deg²)
1 hemispheres = 20626.321318 square degree (deg²)
