Earth

A Metric Planet

Behold each nation on Earth. Find ISO Country Code oval and Time Zone left of flag. See nation or territory name in local language above flag and capital city name (or its approximation) below flag. The eleventh General Conference on Weights and Measures reorganizes and extends Metric System measures in 1960 when this new System is renamed the International System of units or SI after its French initials. For the first time, the world had not merely universal units, but a universal system of units. Not every nation takes full advantage of the System though; some nations procrastinate. Dates below flag show when the System becomes legal or when adopted or when metric implementation becomes compulsory. Date right of flag shows the earlier of those dates. (United Nations Member date is also included.) Listing is generally in geographic order beginning at International Date Line.
Source 1: Adoption and compulsory implementation dates are mostly from Encyclopaedia of Scientific Units, Weights and Measures ISBN 978-1-4471-1122-1 Page 7: The General Conference on Weights and Measures Table 2-2 Adoption and compulsory implementation dates for the metric system (shown below).
Source 2: Some of the dates are from Hector Vera, The Social Life of Measures: Metrication in the United States and Mexico, 1789-2004, PhD dissertation, Sociology and Historical Studies, New School for Social Research, 2011, Pages 494-497.

This is probably the most comprehensive metrication list readily accessible on line with 251 profiles. Every ISO Country Code is represented in this list with four exceptions (GBR HMD BVT UMI). It is pretty obvious how GBR (Great Britain) is a Non-FIFA Country Code. Great Britain is not a nation in the context of matches between nationalistic rivals. Men are instinctively warlike. Sport is a substitute for war. Scotland, England and Wales are distinct nationalities with distinct individual histories. Ireland has an unfortunate political border that should go away according to a majority of the people of Ireland.
One may find a more detailed description (with plenty of pictures) for France, Brasil [Portugal], Germany, Turkey, China, Japan, India and Australia under the Effort tab above.

Weights & Measures — Samoa is officially on the metric system, but in their everyday lives, many residents still calculate distances by the British system used in American Samoa and in the United States. Speed limits are posted in miles per hour, and the speedometers of many local vehicles (most of which have the steering wheels on the left side, in the American and European fashion) show both miles per hour and kilometers per hour.

Metric versus English [Published in 1921] Pages 10 and 11

Having finally made the decision that a system of weights and measures different from any of those then in use was necessary in the interest of simplicity and uniformity, the French Government in 1790 appointed a committee of the Academy of Science to undertake the making of a new system based upon some fundamental scientific measure. Three measures were proposed, namely: the length of a second’s pendulum, the length of a quadrant of a terrestrial equator, and the length of a quadrant of a terrestrial meridian. The committee reported in favor of the terrestrial meridian measure and decided to use the one ten-millionth of a quadrant of the meridian passing through Dunkirk and Barcelona as the standard unit of linear measure under the new system. To this unit of length the designation “meter” was assigned.
