Unit Explanations
Minute of Arc'
Source 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.
Minute Siderealmin_sid
Target UnitA minute sidereal is a unit of time that is defined as 1/60th of a sidereal hour, which is based on the Earth's rotation relative to distant stars rather than the Sun. This results in a duration of approximately 59.83 seconds in standard time. The sidereal minute is particularly relevant in fields such as astronomy and navigation, where precise measurements of time are crucial for locating celestial objects and ensuring accurate positioning. This unit allows astronomers to track the apparent motion of stars and other celestial bodies more accurately than solar time.
Current Use
Today, the minute sidereal is primarily used in astronomy and astrophysics for calculations involving the positioning of stars and celestial objects. Observatories and planetariums utilize this unit to create star charts and to program telescopes for precise tracking of celestial phenomena. It is also used in navigational calculations for spacecraft and satellites, where time measurement relative to the stars is essential for accurate positioning and alignment.
Fun Fact
A sidereal day is about 23 hours, 56 minutes, and 4 seconds long, which is approximately 4 minutes shorter than a solar day.

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.
Etymology: The term 'minute' comes from the Latin 'pars minuta', meaning 'small part'.

Minute Sidereal
time • Non-SI
Definition
A minute sidereal is a unit of time that is defined as 1/60th of a sidereal hour, which is based on the Earth's rotation relative to distant stars rather than the Sun. This results in a duration of approximately 59.83 seconds in standard time. The sidereal minute is particularly relevant in fields such as astronomy and navigation, where precise measurements of time are crucial for locating celestial objects and ensuring accurate positioning. This unit allows astronomers to track the apparent motion of stars and other celestial bodies more accurately than solar time.
History & Origin
The concept of a sidereal minute has its roots in the ancient observations of celestial bodies, where early astronomers noted the difference between solar and sidereal days. The sidereal day, approximately 23 hours, 56 minutes, and 4 seconds, is the duration it takes for the Earth to rotate on its axis relative to the stars. The division of this period into sidereal minutes followed naturally as astronomers began to require finer measurements for their observations. The standardization of this unit took place over centuries of astronomical study.
Etymology: The term 'sidereal' is derived from the Latin word 'sidereus', which means 'of the stars'. It reflects the unit's connection to measuring time based on celestial observations rather than solar events.
Current Use
Today, the minute sidereal is primarily used in astronomy and astrophysics for calculations involving the positioning of stars and celestial objects. Observatories and planetariums utilize this unit to create star charts and to program telescopes for precise tracking of celestial phenomena. It is also used in navigational calculations for spacecraft and satellites, where time measurement relative to the stars is essential for accurate positioning and alignment.
💡 Fun Facts
- •A sidereal day is about 23 hours, 56 minutes, and 4 seconds long, which is approximately 4 minutes shorter than a solar day.
- •The use of sidereal time helps astronomers correctly predict when a star will rise or set.
- •Because the Earth moves in its orbit around the Sun, the position of stars shifts slightly each day, making sidereal time essential for accurate celestial navigation.
