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.
While most of us learn about measuring angles in degrees, there's another unit of angle measurement called the gradian.
A gradian (often abbreviated as grad) is a unit of angle equal to 0.9 (or 9/10) of a degree. It's an alternative to degrees and radians, designed to make some calculations simpler.
Unlike the familiar 360-degree system, a full circle is divided into 400 gradians.
This base-100 system simplifies many geometric calculations:
This makes it an intuitive framework for certain types of angular math.
The conversion between gradians and degrees is straightforward.
Here is the simple gradians to degrees formula:
For example, to convert 200 gradians to degrees, you would calculate: .
When comparing radians vs. gradians, the relationship is key for trigonometry and higher math.
A full circle is 400 gradians or 2π radians.
This means that 200 gradians are equal to π radians. The conversion factor, π/200, is fundamental for calculations that bridge these two systems.
So, why use this system at all?
Gradians are primarily used in specific professional fields like surveying and some branches of engineering, especially in Europe.
The decimal-based nature of the 400-gradian circle simplifies calculations involving right angles, making fieldwork and topographical analysis more efficient.
