Metrication opposition
The spread of metrication around the world in the last two centuries has been met with both support and opposition. All countries except Burma (Myanmar), Liberia, and the United States of America have officially adopted the metric system, although Liberia has seen some introduction of metric units, and in 2013 Burma formally announced the beginning of its metrication program. The metric system has been largely adopted in the United Kingdom, Canada and Ireland, without having fully displaced the imperial units from all areas of life. In other Anglophone countries such as Australia and New Zealand, imperial units have been formally deprecated and are no longer officially sanctioned for use.
