As we all know, some countries use the imperial system (the U.S. use U.S. Customary Units which are different to imperial units) while most use the metric system.

Is the U.K. the only country to use both imperial and metric at the same time?

We use imperial for distance (ie roads), metric for food (if using imperial, metric must also be shown), etc...


The E.U. tried on three occasions to make metric law in the U.K. but eventually they gave in and it was agreed we’d use both and it was made into law.
