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\\))."^^ . "D62" . . "0112/2///62720#UAA096" .
