About These Units
About Grad
The <b>grad</b> is a unit of angle measurement equal to 1/400 circle, 0.01 right angle, 0.9°, or 54'. This unit was introduced in France, where it is called the <b>grade</b>, in the early years of the metric system. The grad is the English version, apparently introduced by engineers around 1900. The name <b>gon</b> is used for this unit in German, Swedish, and other northern European languages in which the word grad means degree. Although many calculators will display angle measurements in grads as well as degrees or radians, it is difficult to find actual applications of the grad today.
About Degree
