U.S. Office Of Education - "Metric Education" (PSA, 1978)
Here's an animated Public Service Annoucement from the U.S. Office of Education - similar in style to the Schoolhouse Rock series - showing us how simple and easy the metric system is... so why haven't we switched over yet?
"Take 10, America!"
This aired on local Chicago TV early Wednesday, March 29th 1978.
