- Second: a 60th part of a minute of arc; "the treasure is 2 minutes and 45 seconds south of here"
- A minute of arc, or arcminute or minute of angle (MOA), is a unit of angular measurement, equal to one sixtieth (1/60) of one degree. This conversion is recognised for calculations involving SI Units. ...
- A unit of angle; 1/60th of an arcminute, or 1/3600th of a degree
- (arc-seconds) {or seconds of arc} an angular measure equal to 1/60th of an arc-minute. Preferred notation [ " or arc-sec].
- 1/3600th of a degree (1 second) of latitude or longitude.
- An arcsecond is a fraction of an arcminute. There ar 60 arcseconds in an arcminute, or 3600 arcseconds in a degree.
- A unit of angular measure. 1 degree = 60 arcminutes. 1 arcsecond = the angular diameter of a penny at 4.12 km (2-1/2 miles).
