The implementation\nconforms to the [SI standard](https://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication811e2008.pdf).\n\n## Installation\n```linux\n$ pip install unit_system\n```  \n\n## Usage\n\n```python\n\u003e\u003e\u003e from unit_system import Quantity\n\u003e\u003e\u003e V = Quantity(1, \"V\")\n\u003e\u003e\u003e A = Quantity(1, \"A\")\n\u003e\u003e\u003e 1*V / (1*A)\n1.0 Ω\n```  \n\nYou can load predefined units like the ones in Mathcad.\n\n```python\n\u003e\u003e\u003e from unit_system import *\n\u003e\u003e\u003e 1*mΩ * 1*A\n0.001 V\n```\n\n## Documentation\nhttps://l-johnston.github.io/unit_system/","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fl-johnston%2Funit_system","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fl-johnston%2Funit_system","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fl-johnston%2Funit_system/lists"}
