unit-system 1.1.7

SI unit system implementation enabling physical quantity math

unit_system

The unit_system package provides a way to do physical quantity math in Python that replicates Mathcad's unit system. The implementation conforms to the SI standard.

Installation

$ pip install unit_system

Usage

>>> from unit_system import Quantity
>>> V = Quantity(1, "V")
>>> A = Quantity(1, "A")
>>> 1*V / (1*A)
1.0 Ω

You can load predefined units like the ones in Mathcad.

>>> from unit_system import *
>>> 1*mΩ * 1*A
0.001 V
