sympy is a great tool for doing units conversions in python: >>> from sympy.physics import units >>> 12. * units.inch / units.m 0.304800000000000 You can easily roll your own: >>> units.BTU = 1055.05585 * units.J >>> units.BTU 1055.05585*m**2*kg/s**2 However, I cannot implement this into my application unless I can convert degrees ...

When I've written something in Python and come to the point where I can run it, there's still no guarantee that no language-specific errors remai...
