I honestly have no idea. I simply did `pip install units` and it worked. If the units module is no longer maintained, then who would write (and maintain) a module that worked with any core python syntax to allow units to be added to quantities? (Note that any core feature would simply allow something like 3_ft to be written to mean the number 3, with some object associated with the name "ft" attached to it - it would be up to a 3rd party module to actually implement the units calculations). It doesn't look like the astropy people want to maintain a generalised units library if they are solely working with numpy arrays. Also, you didn't explain what you meant by "get the final answer" - I'm still not clear with what you want beyond doing the calculation as you showed in your code. > > As has been mentioned, if you don't like "units." then "from astropy import > > units as U" and use "U.ms" of "from astropy.units import ms" and use ms > > directly. > > As an fyi, lots of single-letter variables are commonly used to match > variables in physics and engineering equations.

As I said, there have to be some compromises made.
