 Under debian buster there is a python 2 package
 called python-quantities that apparently
 deals with units via numpy dependencies.
 $ apt-cache show python-quantities
 Package: python-quantities
 Version: 0.12.1-1
 Priority: optional
 Section: python
 Maintainer: Debian Science Maintainers 
 <debian-science-maintainers at lists.alioth.debian.org>
 Installed-Size: 358 kB
 Depends: python (<< 2.8), python (>= 2.7), python:any (>= 2.6.6-7~),
 python-numpy
 Suggests: python-unittest2

 Description-en: Library for computation of physical quantities 
 with units, based on numpy Quantities is designed to handle 
 arithmetic and conversions of physical quantities, which have 
 a magnitude, dimensionality specified by various units, 
 and possibly an uncertainty. Quantities builds on 
 the popular numpy library and is designed to work with 
 numpy ufuncs, many of which are already supported.
 ....
 Also ....
 $ apt-files list python-quantities

 Shows a units sub-directory under /usr/lib/python2.7/dist-packages
 with several individual modules such as force, length, mass, pressue,
 temperature, etc.
 Seems to be also available throug the python package index ....
