1 arcsecond (″) = 0.0000048481 radians (rad). To convert, divide by 206,264.8062: rad = ″ ÷ 206,264.8062. For example, 50,000 ″ = 0.2424068406 rad.
rad = ″ ÷ 206,264.8062

The two units
Arcsecond (″). One sixtieth of an arcminute.
Radian (rad). The angle at which the arc equals the radius; a full turn is 2π radians. Programming maths libraries use radians.
