===== Weights and Measures =====
Should Mars use the [[https://en.wikipedia.org/wiki/Metric_system|metric]] ([[https://en.wikipedia.org/wiki/International_System_of_Units|SI]]) or [[https://en.wikipedia.org/wiki/Imperial_units|imperial]] system? Or something completely different?
This is a question that must be settled, before the first colonists arrive on Mars. We know from Earth, that changing the system, is no small undertaking, so "doing it right" will be of great importance.
