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.
Minute of Arc'
Target UnitA minute of arc, often referred to simply as a 'minute', is a unit of angular measurement equal to 1/60th of one degree. It is denoted by the prime symbol ('). The unit is used in fields such as astronomy, navigation, and engineering to measure small angles with precision. One minute of arc is further subdivided into 60 arcseconds, making it a crucial component in the finer division of angles. It is not an SI unit but is widely used in practical applications due to its straightforward relationship with degrees.
Current Use
Today, the minute of arc is used predominantly in fields requiring precise angular measurements. In astronomy, it helps in locating stars and celestial phenomena. In navigation, it assists mariners and pilots in plotting courses. Engineering applications often utilize minutes of arc in precision measurements and design. Despite the advent of modern technology, these traditional methods remain integral to accurate calculations.
Fun Fact
A full circle has 21,600 minutes of arc.
Convert Second to Minute (s to min)
Convert Seconds (s) to Minutes (min). When you have a raw count of seconds—like 300 seconds—it can be hard to visualize. Converting this to minutes (5 minutes!) makes the duration instantly understandable for human scheduling.
Divide seconds by 60. For example, 90 seconds ÷ 60 = 1.5 minutes.
Second (s)
Definition
The fundamental SI unit of time.
Origins & History
The name comes from 'pars minuta secunda', the second small part of the hour (after the minute). Accuracy has improved from pendulum swings to atomic transitions.
Minute (min)
Definition
Is equal to 60 seconds.
Origins & History
Standardized along with the hour in the middle ages, specifically for astronomical calculations before entering common usage.

Definition
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. 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.
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.
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 Facts

History & Origin
The concept of dividing a circle into 360 degrees has ancient origins, likely stemming from the Sumerians and Babylonians around 3000 BCE, who used a base-60 number system. The minute of arc as a subdivision of the degree emerged from this system as a practical method for detailed angular measurement. This division allowed for more precise calculations necessary in fields like astronomy and navigation.
