PR Summary:

This PR addresses #1057. It provides further explanation about the behind-the-scenes conversion of units, and an example of how to use the reference value parameters to convert to another unit system (mosdef units in this case).

Let me know if anything looks incorrect, or isn't clear.

PR Checklist


  • Includes appropriate unit test(s)
  • Appropriate docstring(s) are added/updated
  • Code is (approximately) PEP8 compliant
  • Issue(s) raised/addressed?

Few formatting changes! Otherwise, this documentation is sorely needed.

To convert the distance units from Angstrom to nm:
use ref_distance = 10 (angstroms/nm)

You can also use the auto_scale parameter to convert distance, energy

You might want to give an example of this as well. I'd move line 98 up above the Examples section, then make a full new:

Examples
-----------

Section with all of these individual examples. See something like this as a format.

I consolidated the examples section here. I see what you're saying about the examples in that other file. Do you think I should write out a full example from imports to creating an mb.Compound, etc.. or just leave these examples specific to picking a value for the reference parameters.
