Pint has no dependencies except Python itself. In runs on Python 2.7 and 3.3+.

You can install it (or upgrade to the latest version) using pip:

$ pip install -U pint

That’s all! You can check that Pint is correctly installed by starting up python, and importing pint:

>>> import pint             
>>> pint.__version__        


If you have an old system installation of Python and you don’t want to mess with it, you can try Anaconda CE. It is a free Python distribution by Continuum Analytics that includes many scientific packages. To install pint from the conda-forge channel instead of through pip use:

$ conda install -c conda-forge pint

You can check the installation with the following command:

>>> pint.test()                 

On Arch Linux, you can alternatively install Pint from the Arch User Repository (AUR). The latest release is available as python-pint, and packages tracking the master branch of the GitHub repository are available as python-pint-git and python2-pint-git.

Getting the code

You can also get the code from PyPI or GitHub. You can either clone the public repository:

$ git clone git://

Download the tarball:

$ curl -OL

Or, download the zipball:

$ curl -OL

Once you have a copy of the source, you can embed it in your Python package, or install it into your site-packages easily:

$ python install
