Convert Arcsec to Deg (Angle)




Description:

Arcseconds are the smallest commonly used unit of angular measurement, equal to 1/3600 of a degree. This conversion is essential in astronomy, satellite tracking, and geodesy, where extremely fine angular resolution is required. One arcsecond equals approximately 0.00027778 degrees.

For example, 1800 arcseconds equals 0.5 degrees — a value that might describe the apparent size of the Moon or the angular separation between stars. In satellite imaging, arcseconds help define precise orbital paths and ground coverage. Converting arcseconds to degrees allows for easier integration into broader calculations involving trigonometry, navigation, and mapping. This relationship is also useful in land surveying, where high-resolution measurements are needed to define property boundaries and terrain features. By translating arcseconds into degrees, professionals can work across scales, from microscopic angular shifts to large-scale geographic layouts.
