User interfaces and programming languages are two different worlds.
Practically all programming languages that support trig operations
use radians for the angular units, which corresponds to mathematical
convention.

Radians are also more natural when you're estimating the values of
trig functions, see your nearest trig book for the formulas.  Without
some way of indicating pi they are much less natural to the user,
though.
