Type
Description

"Arc Second" is a unit of angular measure, also called the $$\textit{second of arc}$$, equal to $$1/60 \; arcminute$$. One arcsecond is a very small angle: there are 1,296,000 in a circle. The SI recommends $$\textit{double prime}$$ ($$''$$) as the symbol for the arcsecond. The symbol has become common in astronomy, where very small angles are stated in milliarcseconds ($$mas$$).
