Radian (rad)
The radian is the main mathematical angle unit and expresses arc length divided by radius.
History: the radian is based on arc length divided by radius and became a natural angular unit in mathematics.
Quickly convert radians to arcseconds without lookup tables or manual math.
This page is focused on converting radians to arcseconds. Type a number into the first field and the result appears immediately in the second field.
Example: 1 rad = 206264.8062470964 ″. Conversion formula: result = value × 1 / 4.8481368110954E-6.
