Arcsecond to Radian (″ to rad)
Convert ″ to rad — Angle converter
Also written as arcsec to rad.
One arcsecond equals 0.0000048481 rad, so to convert arcseconds to radians you multiply the value by 0.0000048481. A arcsecond is smaller than a radian — going the other way, 1 rad = 206264.88 ″. For example, 10 ″ = 0.0000484814 rad and 50 ″ = 0.0002424068 rad.
1 ″ = 0.0000048481 rad
Arcsecond to Radian formula
1 Arcsecond = 0.0000048481 rad
Worked examples
- 25 ″ = 0.0001212034 rad
- 100 ″ = 0.0004848135 rad
