There are two schools of thought on which measurement system the United States should use.
One argument is that the United States of America should switch entirely to the metric system. The United States would have a worldwide communication, since almost every other country uses it. The metric system is easier for everyone to learn because the system is based on ten. It would also make travel easier for the United States and other countries because people would not have to switch between miles and kilometers. The metric system is also what is used for science and most sports. On the other hand, some people would argue that the United States of America should keep the customary system of measure because it would be a lot harder to transition. It would be very costly and difficult for people to learn and re-teach an entirely new system. Generations of Americans have grown up using the customary system, therefore making it harder for them to change. It would also take a large amount of time and money to convert all the cook books, road signs, and gas to the metric system
completely.
Both the metric and customary units of measure are used throughout the world. However, slowly but surely the metric units of measure are spreading to many countries, which is causing everyone to convert to metric. The United States of America is now one of only three countries left who have yet to switch to metric along with Liberia and Myanmar. There are reasons why we should not convert and there are reasons why we should. Overall, the United States of America is having a debate on whether to keep the customary or to convert to the metric system of measurement. As you can see, both sides have good arguments, so it could take some time to completely make the switch to metric if that is what is finally decided.
