# `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](https://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication811e2008.pdf).

## Installation

```linux

$ pip install unit_system

```  

## Usage

```python

>>> 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.

```python

>>> from unit_system import *

>>> 1*mΩ * 1*A

0.001 V

```
