A METRE FOR MARS: METRIC UNITS FOR THE SOLAR SYSTEM

In 1792 Napoleon initiated an ambitious project: the construction of a natural system of measurement, derived from the Earth itself.  The metre was constrained to the length and breadth of our planet - 1/10,000,000th of the circumferential distance from the North Pole to the Equator. It is, literally a measure taken from the Earth and is thus always a reflection of it. 

How then, should we measure elsewhere? Should we not offer other worlds similar opportunities to regulate their own system of standards?
This project embarks upon such a goal: defining a self consistent set of metrics for each planetary body in our solar system. 

I begin with a metre for Mars.

Applying the same circumferential method as used on Earth, a metre of Mars would measure 532.4 mm (in Earth metrics)

I intend to create a metre bar of this length in a ‘Tresca Section’ (as was done with the Earth metre prototype) that will hopefully be produced early 2018.
