Metrication is not because of EU membership

Even though this topic has been done a lot already it is worth re-iterating. Many people in the UK believe that metrication in the UK is a result of UK membership of the European Union (EU), and believe this often repeated lie unquestioningly. The truth is that the UK began its metrication programme in 1965, long before the UK joined the predecessor of the EU, the European Economic Community (EEC), in 1973.  Furthermore, the EU itself was not even created until 1992.

Most Imperial units are not British

One of the myths about Imperial units is that Imperial units are made in Britain. The truth is very different, although Imperial units were defined in the 1824 Weights and Measures Act which made several other traditional units obsolete, the origins of Imperial units, which came from medieval English units of measurement, are not British. 

Imperial units were mostly brought to Britain by the Romans almost 2000 years ago, other units were introduced by the Angles and Saxons from Northern Germany who brought their own measures, the Normans reintroduced Roman style measures, and others were later adopted and modified from medieval French variations of Roman units, known as avoirdupois and troy measures.
