Unit Explanations
Second of Arc"
Source UnitA second of arc, also known as an arcsecond, is a unit of angular measurement that is equal to 1/3600 of a degree or 1/60 of an arcminute. It is used primarily in fields that require precise angular measurement, such as astronomy, navigation, and mapping. An arcsecond is a small unit, reflecting the requirement for high precision in measurements of celestial objects and angles on the Earth's surface. The notation for a second of arc is usually represented by a double prime symbol ("), following the degree and arcminute symbols.
Current Use
Today, the second of arc is indispensable in astronomy for measuring the positions and movements of celestial objects with high precision. It is also used in geodesy and cartography to define the precise angular relationships between points on the Earth. Additionally, arcseconds are employed in the calibration of telescopes and other optical instruments where small angular measurements are critical.
Fun Fact
An arcsecond is roughly the angle subtended by a U.S. dime at a distance of 2.4 miles.

A second of arc, also known as an arcsecond, is a unit of angular measurement that is equal to 1/3600 of a degree or 1/60 of an arcminute.

The notation for a second of arc is usually represented by a double prime symbol ("), following the degree and arcminute symbols.
History & Origin
The concept of dividing a circle into degrees and further into minutes and seconds dates back to ancient Babylonian astronomers, who used a sexagesimal (base-60) number system. The division of a degree into 60 parts, known as minutes, and each minute into 60 parts, known as seconds, allowed for more precise measurement and calculation of angles in the study of celestial bodies. This system became widespread with the work of Greek and later Islamic scholars, who advanced astronomical knowledge and navigation.
Etymology: The term 'second' in this context comes from the Latin 'secunda', meaning 'second division' or 'second order', referring to its place in the hierarchical division of degrees.
