DEGRE. See DEGREE. DEGREE. Though this term properly belongs to geometry, nevertheless it is frequently used both in fortification, and gunnery. Hence it will not be improper to state, that it is a division of a circle, including a 360th part of its circumference. Every circle is supposed to be divided into 360°, parts called degrees, and each degree into 60′, other parts, called minutes; each of these minutes being divided into 60″ seconds, each second into thirds, and so on.
