The metric system runs on tens, and once you know the prefixes, converting between units gets easy. This puzzle collects the base units and the kilo, centi, and milli prefixes that build the rest. It's handy for science and math students moving between grams, meters, and liters. Play it on any device or print it for a measurement lesson.
