How to convert Radian to Arcsecond (rad to arcsec)
To convert Radian to Arcsecond, multiply by 206264.81. The formula is Radian × 206264.81 = Arcsecond. See the example below.
1 Radian = 1 × 206264.81 = 206264.81 Arcseconds
Radian is a unit of angular measurement. One radian is basically the measurement of central angle which intercepts arc s that is equal to radius r of a circle. The symbol for Radian is rad.
Arcsec also known as arc second or second arc is a unit of angular measurement. One second of arc is equal to 1/60 of an arcminute, 1/3600 of a degree, 1/296000 of a turn. That means one full circle will have 1296000 arcseconds. Similar to arcmin, arcsec was originated in Babylonian astronomy as sexagesimal subdivisions of the degree. It is primarily used in fields where most of the work involves working with small angles such as optometry, ophthalmology, and astronomy. In astronomy related work, it is used for comparison of angular diameter of Moon, Sun, and planets. Apart from that, it is also used in cartography and navigation. The symbol for Arcsecond is arcsec.
