The United States is one of the few countries left in the world who still have not converted to using the Metric System as a standardized system of measurement. Instead of going along with what the rest of the world uses, we stubbornly still adhere to using the imprecise Imperial Unit - despite the fact that practically every other country that we interact with uses Metric.
Why should we convert to using the Metric System? Because it’s superior, less convoluted - everything is ordered in units of tens, while the chaotic arrangement of the Imperial System slows things down for us - not only in terms of education, but also businesses, science, foreign relations, and daily life.
