The last two angular units, plane angle and solid angle, are subsidiary units used in the SI, but are treated as dimensionless.
Today, the reference plane for an azimuth is typically true north, measured as a 0?azimuth, though other angular units ( mil ) can be used.
You don't even need to " use " radians, because the relevant relationships are independent of angular units .-- Talk 19 : 40, 21 March 2007 ( UTC)
It is thought that the ancient Chinese astronomers also used " chi " as an angular unit; modern analysis of historical records indicates that it may have been equal to one degree.
Where geographic coordinates are used as the argument of a trigonometric function, the values may be expressed in any angular units compatible with the method used to determine the value of the trigonometric function.
The measure of the angle in another angular unit is then obtained by multiplying its measure in radians by the scaling factor } }, where " k " is the measure of a complete turn in the chosen unit ( for example 360 for degrees or 400 for gradians ):
The external ballistics software program by JBM Ballistics predicts that the bullets of British high pressure . 338 Lapua Magnum cartridges using 16.2 g ( 250 gr ) Lapua LockBase B408 bullets fired at 936 m / s ( 3, 071 ft / s ) muzzle velocity under International Standard Atmosphere conditions at elevation ( air density ? = 1.1069 kg / m 3 ) and assuming a flat fire scenario ( a situation where the shooting and target positions are at equal elevation ) and a zero ( the distance at which the rifle is sighted in ) arrive at distance after approximately 6.017 seconds flight time at 251.8 m / s ( 826 ft / s ) velocity and have dropped 120.95 m ( 396.8 ft ) or in angular units 48.9 milliradian ( 168 MOA ) on their way.
