Original: For example , an angle of 1.2 radians would be written as '' 1.2 rad '' or '' 1.2 c '' ( the second symbol is often mistaken for a degree : '' 1.2 ° '' ) .
Simplified: It is shown by the symbol '' rad '' or , less often , c ( for circular measure ) . A '' milliradian '' is 1/1000 of a radian .
