[edit] Summary

World Map showing Metrication, color-coded by year of conversion. Using data from USMA (U.S. Metric Association) here.

(Note regarding the United Kingdom and the United States: Data indicates UK was metric in the 1960s - they made a decision to go metric in the 60's and made a legal commitment to do so in 1973 as part of its conditions for membership in the EEC (now EU), but then did almost nothing about it. The UK now uses metric however, and it is illegal to sell products weighed only in imperial measurements, imperial measurements have not been taught in schools since the mid 90's either. This is similar to the situation occurring in the US, where metric is the 'official' system for lengths and weights, though its metrication process has been very slow due to public pressure and lack of funding.)
