Metric Today: Did You Know That

摘要

Martin Morrison notes that the following 4-minute video pleasantly and factually presents the need to convert to the metric system. He highly recommends it, despite a few minor quibbles. "Why The US Won't Switch To The Metric System" http://digg.com/video/celsius-fahrenheit-metric-imperial-america. In an unrelated event, Morrison was surprised to see a television ad for Hershey's PayDay candy bars entirely in metric units. The ad compared the length of its old and new bars and gave the lengths in centimeters, not inches. https://www.youtube.com/watch?v=vmXglmuj6cQ.
