Sextant to Arcminute Converter

A sextant is a unit of angular measurement equal to 1/6 of a full rotation, or 60 degrees. It represents one of six equal sections when a circle is divided into six parts.

The sextant as an angular unit is related to the navigational instrument of the same name, developed in the 18th century. The division of circles into six parts (hexagonal division) has ancient roots in geometry, as 60 degrees represents the angle in an equilateral triangle.

Sextants as angular units are rarely used in modern applications, though the 60-degree angle remains important in crystallography, molecular geometry, and some engineering applications. The term is more commonly associated with the navigational instrument rather than the angular unit itself.

An arcminute (′) is a unit of angular measurement equal to 1/60 of a degree. It provides finer precision than degrees for measuring small angles, particularly useful in astronomy and navigation.

Arcminutes developed from the Babylonian base-60 system, where each degree was subdivided into 60 minutes. The term 'minute' comes from the Latin 'pars minuta prima' meaning 'first small part'. This subdivision system has been used in astronomy and navigation for over 2,000 years.

Arcminutes are extensively used in astronomy for measuring celestial object positions and separations, in surveying for precise land measurements, and in navigation for GPS coordinates. They're also used in optics for measuring angular resolution and in artillery for targeting calculations.
