Even the metric world uses factors other than 10. Does anyone remember the history behind the factors 60 & 360? e.g., 60 sec/min, 360 deg/cycle. Having worked in a standards group at one time, I know there is a lot of politics & parochialism involved behind the scenes, especially when it's international. For all practical purposes, "metric" really meant european, for better or for worse. IMHO, the change from descriptives such as cps (cycles per second), psi, etc. was unfortunate. Those made sense. But Hertz? I do support the change to a decimal system, not because it's necessarily always better, but because it's now universal. Having different measurement systems helps no one. //Jack |
