You can convert between all astronomical coordinate systems with the CooC. Online versions offer a form with which you can easily convert one coordinate to another. Downloadable versions are older and a bit crummy but you can convert any number of coordinates in one go.

N.B. A major problem with online version has been corrected! If you still results from or to other coordinate systems than the ones you selected, try to click the REFRESH or RELOAD button on your browser when on the result page.
