pypuq 1.3.8

Physical Units and Quantities for Python

Physical units and quantities for Python

This module is a Python binding of the C++ library scnt-puq. You can read more about this module and its functionality in the SciNumTool documentation.

Installation

To start, one has to install the scnt-puq library. On macOS this can be easily done using homebrew formula:

brew tap vrtulka23/scinumtools
brew install vrtulka23/scinumtools/scnt-puq

After that, one can proceed with the usual PyPi installation:

pip3 install pypuq

Examples of use

As already mentioned, pypuq is a binding to the standalone C++ library scnt-puq. Therefore, pypuq inherits all its usual functionality. However, the Python interface of exposed classes (Quantity, UnitSystem) is slightly adapted.

>>> from pypuq import Quantity
>>> 
>>> q = Quantity(16, 'm')
>>> r = Quantity(223, 's')
>>> speed = (q/r).convert('mph')
0.0717489*m*s-1

More examples and explanation are available in the SciNumTools documentation. You can also look at the test problems in the pytest directory.
