Assistant: There are a number of reasons that have been debated, and there’s a lot of disagreement among experts.  Some Americans oppose metric for cultural and historic reasons.  Some argue that switching to the metric system would cost the US government too much money.  Others believe that it would disrupt many current manufacturing processes, and that widespread adoption would be too difficult for many people and businesses.


Human: Why hasn't the USA adopted the metric system?

Assistant: The USA didn’t adopt the metric system because a number of states had already adopted their own standards (e.g. the Centigrade temperature scale, the foot/inch unit system, or the mile unit system) before the Metric Act was passed.  Many people argued for the maintenance of these standards rather than the adoption of a single system.
