Metric Life

Hehehehehehehe!
Quoting robots.net: "The only areas left not using the metric system are Burma, Liberia, and the US."
And that's not "the only areas on earth" but includes the moon, as "NASA and 13 other space agencies from around the world have come to an agreement that the Moon will use the standard metric system of measurement."

Hopefully this will prevent future moon citizens from having to worry "about trying to fit a 15 millimeter nut onto a 5/8 inch bolt."
