Arcmin

Arcmin An arcmin, also known as an arcminute or minute of arc, is a unit of angular measurement equal to 1/60th of a degree. It is denoted by the symbol ′. There are 60 arcminutes in one degree, and 360 degrees in a full circle. The arcminute is commonly used in fields such as astronomy, optics, and geography to measure small angles.

Definition

An arcminute is defined as:

• 1 arcminute = 1/60th of a degree
• 1 degree = 60 arcminutes
• 1 arcminute = 60 arcseconds

Usage

Arcminutes are widely used in various scientific disciplines:

• In astronomy, arcminutes are used to describe the apparent size of objects in the sky. For example, the Moon and the Sun both have an apparent diameter of about 30 arcminutes when viewed from Earth.
• In optics, arcminutes are used to specify the resolution of optical instruments such as telescopes and microscopes.
• In geography, arcminutes are used in the context of latitude and longitude to describe precise locations on the Earth's surface.

Conversion

Arcminutes can be converted to other units of angular measurement:

• 1 arcminute = 60 arcseconds
• 1 arcminute ≈ 0.0166667 degrees
• 1 arcminute ≈ 0.000290888 radians
