Umdrehungen in Bogenminuten Rechner

A turn (tr), also called a revolution, represents one complete rotation of 360 degrees or 2π radians. It is used in engineering contexts involving rotational mechanics, electric motor specifications, and angular velocity calculations where whole rotations are more intuitive than degrees or radians. One turn equals exactly 360 degrees.

The arcminute (′) equals 1/60 of a degree, used in astronomy, cartography, and precision navigation where fine angular resolution is needed. Stars are cataloged by their coordinates in degrees and arcminutes, and telescope pointing accuracy is often specified in arcminutes. One arcminute equals 1/60 degree or about 0.000291 radians.
