Long-shot Democratic presidential hopeful Lincoln Chafee wants to put the country on the metric system.
"There are only two other countries that aren't metric, Myanmar and Liberia. And so it's time for America not only economically but symbolically to join the rest of the world," Chafee, a former governor and U.S. senator from Rhode Island, said.
"I know that many in the scientific community, the health care community, that have to deal internationally, the business community, are saying this is way overdue," Chafee added. "Ronald Reagan talked about it. Others have talked about it."
