What is Barril?

Python package to manage units for physical quantities.

Quick example:

.. code-block:: python

from barril.units import Scalar

s1 = Scalar(10, 'm')
s2 = Scalar(500, 'cm')
assert s1 + s2 == Scalar(15, 'm')

Features

• Pre-defined unit database containing several physical quantities for the Oil & Gas industry.
• Data types with an associated unit: Scalar, Array, Quantity, FixedArray.
• Automatic conversion during arithmetic operations.
