Voyager 1 will be 4 Plutos away whether we use metric or not. Putting large numbers in context helps understand them. "Muricans" know it, and so do Europeans at the European Space Agency. Here's what they write about the International Space Station: > At 28 800 km/h it only takes 92 minutes for the weightless laboratory to make a complete circuit of Earth. Astronauts working and living on the Station experience 16 sunrises and sunsets each day. They could have left it at 28 800 km/h - which is metric - and call it a day. But they went an extra mile (or should I say an extra 1.6 kilometer) to put that number into perspective.
