I was wondering what kind of constants this would include. Physical constants, or just mathematical ones? And what about constants with multiple expressions depending on units? For example, H_bar = 6.626e-34 J-s = 4.135e-15 eV-s.
IMO, We should definitely use SI.

What units to use is strictly a function of what you are simulating. I'm a big fan of SI units in education and many problems, but in some settings they are not a good choice. (Consider a particle physics program, as an example.) In physical calculations, you should always choose your units based on what calculations you are doing, not on some rigid belief in what system people "should" use. This has some flexibility based on what units users of the program will expect to see, but none based on pure dogma. John
