Arcsecond (arcsec)

An arcsecond is 1/60 of an arcminute, or 1/3600 of a degree. It is commonly used in precise scientific and astronomical contexts.

Radian (rad)

A radian is the SI unit of angular measure. One radian is the angle created when the arc length equals the radius of a circle.

How to Convert Arcseconds to Radians

Conversion factor:

1 arcsec=0.00000485 rad1\,\text{arcsec} = 0.00000485\,\text{rad}

Inverse factor:

1 rad=206264.80625 arcsec1\,\text{rad} = 206264.80625\,\text{arcsec}

Example

Convert 15 arcsec to rad:

rad=arcsec×0.00000485\text{rad} = \text{arcsec} \times 0.00000485
rad=15×0.00000485\text{rad} = 15 \times 0.00000485
rad=0.00007272\text{rad} = 0.00007272
=0.00007272 rad= 0.00007272 \, \text{rad}
