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 square degree unit is a non-SI unit measure of a solid angle. 1 deg2 is equal to 3.04617×10−4 sr.
Divide the square degree value by 3282.778544
steradian = square degree / 3282.778544
Multiply the steradian value by 3282.778544
square degree = steradian x 3282.778544
One steradian (sr) is equal to 3282.778544 square degree (deg²)
1 steradian (sr) = 3282.778544 square degree (deg²)
One square degree (deg²) is equal to 0.000305 steradian (sr)
1 square degree (deg²) = 0.000305 steradian (sr)
