Traditionally, the three countries listed as not using the metric system are the USA, Liberia, and Burma (Myanmar).
I just learned that Belize is also in that camp. From the Huffington Post: Belize's court system is based on British common law, familiar to most of us. And unlike the rest of Latin America, measurements here are in inches, feet, miles, and acres -- so no metric conversions are necessary. And from Frommer's Fast Facts: Measurements -- English measurements are the norm in Belize, although the metric system is making slight inroads. However, it does sound like Burma and Liberia are making some moves towards metric, which I presume leaves the USA and Belize as the last die-hard holdouts! Ezra
