21.2 arcsec = 0.000102781 rad. To convert arcseconds to radians, multiply by 0.000004848139: 21.2 × 0.000004848139 = 0.000102781.
How to convert arcseconds to radians
rad = arcsec × 0.000004848139
- 1 arcsec = 0.000004848139 rad (and 1 rad = 206,264.71 arcsec).
- Multiply the amount by the factor: 21.2 × 0.000004848139 = 0.000102781.
- Answer: 21.2 arcsec = 0.000102781 rad.
