A solid angle (symbol: Ω) the SI base unit is steradian or square radian.
The steradian or square radian. It is used in three-dimensional geometry, which quantifies planar angles.
A hemisphere unit has 2π steradians. The complete sphere has a solid angle of 4π steradians.
Multiply the hemispheres value by 6.283190
steradian = hemispheres x 6.283190
Divide the steradian value by 6.283190
hemispheres = steradian / 6.283190
One steradian (sr) is equal to 0.159155 hemispheres
1 steradian (sr) = 0.159155 hemispheres
One hemispheres is equal to 6.283190 steradian (sr)
1 hemispheres = 6.283190 steradian (sr)
