One arc second is one 3600th of a degree.
If you are talking about angles, a second is one sixtieth of a minute. A minute is one sixtieth of a degree. Soooo, a second is one 3600th of a degree (60 times 60)
The word second is in English already. It means either in position 2 or a unit of time or an angular division equivalent to one 3600th of a degree.
An arc second is 1/60th of an arc minute and 1/3600th of a degree. This means there are 60 arc seconds in an arc minute, and 3600 arc seconds in a degree.
3600th
