##### How to Convert 21 Arcseconds to Octants (arcsec to octant)

By using our Arcsecond to Octant conversion tool, you know that one Arcsecond is equivalent to 0.0000061728395061728 Octant. Hence, to convert Arcsecond to Octant, we just need to multiply the number by 0.0000061728395061728. We are going to use very simple Arcsecond to Octant conversion formula for that. Pleas see the calculation example given below.

Convert 21 Arcsecond to Octant 21 Arcsecond = 21 × 0.0000061728395061728 = 0.00012962962962963 Octant

##### What is Arcsecond Unit of Measure?

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.

##### What is the symbol of Arcsecond?

The symbol of Arcsecond is arcsec which means you can also write it as 21 arcsec.

##### What is Octant Unit of Measure?

Octant is a unit of angular measurement. One octant is equal to 45 degrees. It measures an angle up to 90 degrees with the help of 45 degree arc and reflecting optics which basically doubles the angle.

##### What is the symbol of Octant?

The symbol of Octant is octant which means you can also write it as 21 octant.
