This map is posted in response to the ridiculous graphic that suggests the U.S. is the only major economy still using a system of measure besides metric.
Countries that primarily or partially use systems of measurement besides metric are all correctly filled in on our map, big or small.
In fairness, all countries use non-metric units to some extent, so there really shouldn’t be any red countries that are “all metric.”
Even the French use “livres” and “pouces” in the market and in farming, respectively.
The use of the inch and foot are almost international. There are less than ten countries on Earth that don’t use the foot, and there aren’t any that don’t use the inch in tires that we have found.
