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. "When we made the announcement at the meeting, the reps for the other space agencies all gave a little cheer," says Jeff Volosin, strategy development lead for NASA's Exploration Systems Mission Directorate. In part this decision was made to avoid future problems like the loss of the Mars Climate Orbiter robotic probe that was caused by NASA software that used olde Imperial units instead of metric. When the software interpreted newtons as furlongs per fortnight (or something equally obscure), the robot missed its orbital insertion and burned up in the atmosphere. The decision to go metric will greatly simplify life on the moon for future explorers, who won't have to buy two sets of wrenches or "worry about trying to fit a 15 millimeter nut onto a 5/8 inch bolt." This also adds 27% more land area to the portion of the solar system using the metric system. The only areas left not using the metric system are Burma, Liberia, and the US.
