A turn is a unit of plane angle measurement equal to 2π radians, 360° or 400 gon. A turn is also referred to as a revolution or complete rotation or full circle or cycle or rev or rot.

A turn can be subdivided in many different ways: into half turns, quarter turns, centiturns, milliturns, binary angles, points etc.

Subdivision of turns

A turn can be divided in 100 centiturns or 1000 milliturns, with each milliturn corresponding to an angle of 0.36°, which can also be written as 21′ 36″. A protractor divided in centiturns is normally called a percentage protractor.

Binary fractions of a turn are also used. Sailors have traditionally divided a turn into 32 compass points. The binary degree, also known as the binary radian (or brad), is ¹⁄₂₅₆ turn. The binary degree is used in computing so that an angle can be represented to the maximum possible precision in a single byte. Other measures of angle used in computing may be based on dividing one whole turn into 2ⁿ equal parts for other values of n.

In swimming, a turn is a reversal of direction of travel by a swimmer. A turn is typically performed when a swimmer reaches the end of a swimming pool but still has one or more remaining pool lengths to swim.

Microsoft Academic Search was a free public search engine for academic papers and literature, developed by Microsoft Research for the purpose of algorithms research in object-level vertical search,data mining, entity linking, and data visualization. Although largely functional, the service was not intended to be a production web site and has all but been taken offline, as was originally intended when the research goals of the project had been met. According to a 2014 publication on arXiv, the service has not been updated since 2013 and seen a marked decline in the number of indexed documents since 2011. The fact that this decline has not been reported on earlier indicates to the authors that the service was largely ignored by academics and bibliometricians alike.

Microsoft Academic is a semantic network consisting of the bibliographic information (metadata) for academic papers published in journals, conference proceedings, as well as authors, journals, conferences, and universities. As of February 2014, it has indexed over 39.9 million publications and 19.9 million authors.
