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 ....
