An arcminute (plural: arcminutes) is a precise unit of angular measurement, equal to 1/60th of a degree.
It provides a way to measure very small angles with high accuracy and is frequently used in scientific and technical fields. The common abbreviation for arcminute is arcmin.
There are precisely 60 arcminutes within a single degree.
This relationship is a core part of the "degrees, minutes, seconds" (DMS) system of measurement, which breaks down angles into smaller parts for greater precision.
The universally recognized symbol for an arcminute is the prime symbol (′).
This symbol is placed directly after the number to denote the measurement. For example, an angle of 45 and a half degrees can be expressed as 45° 30′.
Arcminutes are essential in fields that demand precise angular resolution. Key applications include:
Astronomy: Astronomers use arcminutes to measure the apparent size of celestial objects as seen from Earth and the distance between them in the sky.
Navigation: In celestial navigation and cartography, one arcminute of latitude along any meridian on the Earth's surface is approximately equal to one nautical mile.
Surveying: Surveyors use arcminutes to measure land boundaries and features over long distances accurately.
An arcsecond (arcsec) is a tiny unit of angular measurement, equal to 1/3600th of a degree.
To put that in perspective, one arcsecond is roughly the angular size of a dime viewed from over a mile away. As a unit in the International System of Units (SI), it's essential for measuring extremely small angles with high precision.
Arcseconds are fundamental in astronomy for measuring the apparent size and separation of celestial objects as seen from Earth.
Because stars and galaxies are so distant, their angular size in the sky is incredibly small. Astronomers use arcseconds to precisely quantify the separation between double stars, the diameter of distant galaxies, and the intricate details of nebulae.
This level of precision is also critical for calculating stellar parallax. This is a method used to determine the distances to nearby stars by measuring their slight shift in position against a distant background as the Earth orbits the Sun over six months.
The arcsecond is directly used to define the parsec (pc), a primary unit for measuring astronomical distances.
A parsec is defined as the distance at which a star would have a parallax angle of exactly one arcsecond. In other words, if an object is one parsec away, it will appear to shift by one arcsecond in the sky as the Earth moves from one side of its orbit to the other.
This direct relationship makes the arcsecond indispensable for building the cosmic distance ladder and mapping the vastness of space.
Beyond the cosmos, arcseconds are crucial for high-precision geography, cartography, and navigation right here on Earth.
Latitude and longitude coordinates are expressed in degrees, minutes, and arcseconds. One arcsecond of latitude corresponds to a nearly constant distance of about 30.92 meters (101.4 feet) on the Earth's surface.
This allows for the highly accurate location pinpointing that is essential for modern GPS systems, land surveying, aviation, and any application requiring precise geographic positioning.
