GitHub - python-quantities/python-quantities: Quantities package for the python programming language
Quantities is designed to handle arithmetic and conversions of physical quantities, which have a magnitude, dimensionality specified by various units, and possibly an uncertainty. See the
for examples. Quantities builds on the popular numpy library and is designed to work with numpy ufuncs, many of which are already supported. Quantities is actively developed, and while the current features and API are stable, test coverage is incomplete so the package is not suggested for mission-critical applications.
A Python package for handling physical quantities. The source code and issue tracker are hosted on GitHub:

Here is a simple example:
>>>importquantitiesaspq>>>distance=42*pq.metre>>>time=17*pq.second>>>velocity=distance/time>>>"%.3f %s"% (velocity.magnitude, velocity.dimensionality) '2.471 m/s'>>>velocity+3Traceback (mostrecentcalllast): ... ValueError: Unabletoconvertbetweenunitsof"dimensionless"and"m/s"Installation
To install quantities itself, simply run:
$ pip install quantities Tests
To execute all tests, install pytest:
$ python -m pip install pytest And run:
$ pytest in the current directory. The master branch is automatically tested by GitHub Actions.
