About Second
The <b>second</b> is a unit of angular measure equal to 1/60 arcminute. This unit is also called the <b>arcsecond</b> to distinguish it from the second of time. One second is a very small angle indeed: there are 1 296 000 seconds in a circle. The SI defines s as the symbol for the time unit and recommends <b>"</b> as the symbol for the arcsecond. The international standard ISO 31 recommends that angles be stated in degrees and decimal fractions of the degree, without use of arcminutes and arcseconds.
