A physical quantity calculator.
Project description
Demo
Rest mass of an electron
>>> me
9.1093837015e-31 kg
Speed of light
>>> c
299792458.0 m * s**-1
Rest energy of an electron
>>> me * c**2
8.187105776823886e-14 m**2 * s**-2 * kg
In mega electronvolts
>>> me * c**2 / MeV
0.5109989499961642
This matches the rest energy of electron on Wikipedia.
Usage
Install this module using pip via pip install electronvolt
.
For best experience, use in an interactive python environment, e.g. jupyter notebook, and import using from electronvolt import *
.
Alternatively, run this module online HERE. This page typically loads in 3 minutes. Use shift+enter to run a block of code. Run the first block to initialize the calculator. Run the second block to feel how it works.
