Fair, I was mostly thinking electrical engineering and similar. For civil engineering, I'm curious what is common. As soon as you have Fourier and/or Laplace Transforms, you will most likely end up using radians, and are these not relevant for civil engineering? I have no idea, though the modeling of linear, time-invariant systems (i.e. filters) strike me as important if you're building, say, a bridge, and/or care about seismic activity at all.

Nevertheless, in the context in which this was presented, radians are the only way to go.
