# GNU units conversion program - short introduction

## Introduction

A re-occcuring problem in science and engineering is the correct conversion of one unit (say metre) into another (say yard). Usually, it is just a matter of working out the conversation factor but - if things go wrong - it can been …

# Physical quantities (numerical value with units) in Python

Using 'physical quantities' - objects that carry a number and a physical unit. All in Python. (Python 2)

# Performance of Python's long data type

How fast is Pythons (software) data type long?

# Setting up Pelican - how to make equations work?

Seeing that I have solved this problem twice (forgetting the solution after having done it once), I will write down the essential steps.

To be able to use equations in the static Pelican Blog generator, the key is to include a code snippet like
