I'm hooked on a new time-wasting pastime... looking for nutty units of measurement and conversion factors at onlineconversion.com. The only rule is that you must put the larger unit on the left, so that the conversion factor is greater than 1. So far I've mostly played in the Length/Distance section, and I have already discovered that Q (sometimes called kyu) is a unit of length equivalent to a quarter of a millimeter. Which means that every time you travel a kilometer you've crossed four million of me! Other length facts you should obviously know:1 U = 177.8 Q 1 finger = 2 nail 1 arms-length = 70 centimeter 1 gnat's eye = 1.25 hair's breadth 1 klick = 328.0839895 stick 1 smoot = 96,479.3922558 twip 1 gigaparsec = 123,427,119,999,999,984,616,376,584,024.2342712e+29 QIf you switch over to the Weight/Mass section, you might learn that1 slinch = 1,948,343.2830839 crith The Dictionary of Units of Measurement is a good place to look up more information about some of these obscure measurements.
