| The '''gradian''' is a unit of plane [[angle]], equivalent to {{frac|1|400}} of a [[turn (geometry)|turn]].<ref>{{cite book|url=http://webdav-noauth.unit-c.fr/files/perso/pbarbier/cours_unit/Elements_de_base_de_la_cartographie.pdf|page=12|date=2005|publisher=Institut Géographique National|author=Patrick Bouron|accessdate=2011-07-07|title=Cartographie: Lecture de Carte}}</ref>

| | |
| It is also known as '''gon''', '''grad''', or '''grade'''. One grad equals {{frac|9|10}} of a [[degree (angle)|degree]] or {{frac|[[pi|π]]|200}} of a radian. In continental [[Europe]], the French term ''centigrade'' was in use for one hundredth of a grad, and the term ''myriograde'' was in use for one ten-thousandth of a grad. This was one reason for the adoption of the term [[Celsius]] to replace centigrade as the name of the temperature scale.{{Citation needed|date=October 2012}}
| |
| | |
| == History ==
| |
| The unit originated in [[France]] as the ''grade'', along with the [[metric system]]. Due to confusion with existing ''grad(e)'' units of northern Europe, the name ''gon'' was later adopted, first in those regions, later as the international standard. In [[German language|German]], the unit was formerly also called ''Neugrad'' (new degree), likewise ''Nygrad'' in [[Swedish language|Swedish]], [[Danish language|Danish]] and [[Norwegian language|Norwegian]] (also ''Gradian''), and ''Nýgráða'' in [[Icelandic language|Icelandic]].
| |
| | |
| Although attempts at a general introduction were made, the unit was really only adopted in some countries and for specialised areas, like [[surveying]]. The French artillery has used the grad for decades. The degree, {{frac|1|360}} of a circle, or the mathematically more convenient radian, {{frac|1|(2π)}} of a circle (used in the [[SI]] system of units) are generally used instead. In the 1970s and 80s most [[scientific calculator]]s offered the grad as well as radians and degrees for their [[trigonometric functions]], but in recent years most offer degrees and radians only{{Citation needed|date=April 2011}}.
| |
| | |
| The international standard symbol for this unit today is "gon" (see [[ISO 31-1]]). Other symbols used in the past include "gr", "grd", and "g", the last sometimes written as a superscript, similarly to a degree sign: 50<sup>g</sup> = 45°. "Grad" was commonly used on calculators with LCD displays, as "DEG", "GRAD", and "RAD" could all be represented as a subsection of a panel with the letters "DEGRAD".
| |
| | |
| ==Benefits==
| |
| | |
| Each quadrant is assigned a range of 100 gon, which eases recognition of the four quadrants, as well as arithmetic involving perpendicular or opposite angles.

| |
| | |
| One advantage of this unit is that right angles are easy to add and subtract in mental arithmetic. If one is traveling on a course of 117 gon (clockwise from due North), say, then the direction from one's left is instantly convertible into 17 gon; while the direction from one's right is 217 gon; and the direction from behind one is 317 gon. A disadvantage is that the common angles of 30° and 60° in geometry must be expressed in fractions (33{{frac|1|3}} gon and 66{{frac|2|3}} gon, respectively). Similarly, in one hour ({{frac|1|24}} day), Earth rotates by 15° or 16{{frac|2|3}} gon.
| |
| | |
| Originally, 1 gon of arc along the Earth's surface was equal to 100 kilometers of distance at the [[equator]]; therefore 1 centigrad of arc equals 1 kilometer.<ref>[http://webdav-noauth.unit-c.fr/files/perso/pbarbier/cours_unit/Elements_de_base_de_la_cartographie.pdf Cartographie – lecture de carte – Partie H Quelques exemples à retenir]</ref>
| |
| | |
| Gradians are also convenient when working with vectors on the [[complex plane]]. The exponent of the [[imaginary unit]] on any given vector is equal to its angle (''argument'') in hectogradians (100 gon) from the positive x-axis: <math>i^n</math> has an argument of <math>100n</math> gradians.
| |
| | |
| ==Use in surveying ==
| |
| In surveying, the gradian is the default unit of angles in many parts of the world. Subdivisions of gradian used in surveying are c's (1 c = 0.01 grad) and cc's (1 cc = 0.0001 grad).
