The correct answer to the question "How do you say 'angle unit seconds' in English?" is 'arcsecond'.
In angular measurement, an 'arcsecond' is the smallest unit of measurement for angles. It is denoted by the symbol "″". One arcsecond is equal to 1/60th of an arcminute or 1/3600th of a degree. The term 'arcsecond' is derived from its relationship to a circle, where an angle of 360 degrees is divided into 60 arcminutes and each arcminute is further divided into 60 arcseconds.
Arcseconds are commonly used in various scientific and astronomical calculations, as they allow for precise measurements of extremely small angles. For example, in astronomy, the angular size of celestial objects, such as stars or galaxies, are often measured in arcseconds. The term 'arcsecond' is widely recognized and used in the scientific community to communicate precise angular measurements.
