Submitting the requested conversion queries to this resource gave the following answers. 1 hartree = 4.359748e-18 joule 1 calorie = 4.1868 joule (fewer than the requested six significant figures) 1 bohrradius = 0.5291772 angstrom This server is often busy, so reference to a manual will often provide the answer quicker.
