Although downvoted, this is the right response. Its not harder for the US to move to metric than it was for any other large country. The change hasn't happened because there isn't utility in using metric, and a lot of cost. Of course, there are clear examples when metric is both easy an intuitive. In everyday usage there are many cases where Imperial is beneficial (cooking -- metric is poor for individual servings, height and weight metric is inefficient as the modal height starts with the same digit, temperature requires more digits).
