Convert Revolution to Degree (r to °)

Revolution (r) and Degree (°) are both units of angle. With the conversion form below, you can effortlessly and accurately convert revolution to degree. This free online calculator tool makes it simple and easy to perform the conversion from r unit to the ° unit.

An angle is a measure of the rotation between two rays that share a common endpoint (vertex). The most common unit is the degree (°), where a full circle = 360°. The SI-derived unit is the radian (rad), where a full circle = 2π rad ≈ 6.2832 rad; one radian is the angle subtended at the centre of a circle by an arc equal in length to the radius. Other units include the gradian (grad) (400 grad = full circle) and the arcminute (′) and arcsecond (″), widely used in astronomy and navigation.

A degree (symbol: °) is a widely used unit of angle, equal to 1/360 of a complete rotation. Degrees are commonly used in mathematics, geometry, engineering, surveying, navigation, astronomy, construction, and everyday applications to measure the size of an angle. Although the SI unit for plane angle is the radian, the degree is accepted for use with the International System of Units (SI) and remains the most familiar angular unit worldwide.

One full circle contains 360 degrees, a right angle measures 90°, and a straight angle measures 180°. Degrees can also be divided into 60 arcminutes (′), with each arcminute further divided into 60 arcseconds (″) for greater precision in surveying, astronomy, and geodesy.

Degrees are used to specify compass bearings, map directions, road and railway curves, machine rotation, solar elevation, geographic coordinates, and the orientation of buildings and structures. Their intuitive scale and widespread adoption make degrees the standard unit for expressing angles in education, engineering drawings, navigation systems, and many scientific disciplines.
