I'd recommend you to get used to using radian measurement; though it may
initially looks unfamiliar, working in radian (with computer or by-hand)
is much more natural once you get used to it. Many formulaes become
simpler when using radian while some are only valid in radian.

The only reasonable point where you should convert from and between
radians is when requesting input from non-mathematician users.
