# Demo
#### Import module
```python
>>> from electronvolt import *
```
#### Rest mass of an electron
```python
>>> me
9.1093837015e-31 * kg
```
#### Rest energy of the electron, in [SI](https://en.wikipedia.org/wiki/International_System_of_Units) units
```python
>>> me * c**2
8.187105776823886e-14 * m**2 * s**-2 * kg
```
#### In mega electronvolts
```python
>>> me * c**2 / MeV
0.5109989499961642
```
This matches the electron rest energy on [Wikipedia](https://en.wikipedia.org/wiki/Electron_rest_mass).
# Usage
Install via `pip install electronvolt`.
#### Alternatively, run this module [online](https://mybinder.org/v2/gh/dw61/electronvolt/HEAD?filepath=online.ipynb)
* Typically loads within 3 minutes.
* Shift+enter to run a block of code. Run first block to initialize the calculator.
