Astronomers don't use degrees in sky positions of "longitude", but instead divide the sky into 24 "hours" of 'right ascension', each of which corresponds to 15 degrees of sky 'longitude', meaning that there is an exact conversion between the two. But sky positions are always given as "right ascension" and "declination" (= latitude, ranging like normal from -90 to +90 degrees). lojbab
