This article addresses the question why the United States does not use the metric system like the rest of the world when it was supposed to be in use by the 1980s. The expert Ian MacGregor analyses this question from two aspects. On the one hand, Ian Macgregor believes the economic problem is one reason. If the United States were to switch to the metric system, existing factory machines and infrastructure would need to be retooled and adapted to the new system. It's going to be a huge expense. In addition, the size of the North American market is sufficient for individuals and groups to abandon the difficult task of converting and continue to operate as usual. On the other hand, the experts argues that people are used to the old system, that they think the metric system is foreign and suspicious and teaching the masses a new system is a costly and difficult task. As a result, people refused to use the new metric system. In my future class, when I teach the students the metric system, the students may ask me why the U.S. is not metric. At first, I will ask them to use the critical thinking to think by themselves. Then, I will share those valid reasons from this article with my students. In addition, I may ask them to contrast the advantages and disadvantages of the American system and metric system and lead students to analyze that with the influence of the globalization whether the U.S will use the metric system in the future.

This addresses two interesting questions - the limits of Uncertainty and why the US is not Metric. Both answers are easy to understand and share with students and I have always shared the problems of the US not being metric with mine.
