Take the trigonometric sine of the data in place.
Units are accounted for in the calculation. For example, the the sine of 90 degrees_east is 1.0, as is the sine of 1.57079632 radians. If the units are not equivalent to radians (such as Kelvin) then they are treated as if they were radians.
The Units are changed to ‘1’ (nondimensionsal).
