That's because road signs were in metric so you did not need to convert is my guess. With exception for bridges, there are no signs for heights on the roads. It's a SHAME (on Burma, Liberia and the United States) that with all microcontrollers in any electronic device these days we still don't use SI in daily life. American machine shops rarely use metric in my experience. Same goes for hardware stores, metal suppliers, food containers, cookie recipes, weather, GPS, etc. http://en.wikipedia.org/wiki/SI and when they do use it, it's not correct in most cases, see specs for stepper motor torque in kg-cm instead of Nm by many online sellers. Local HW store sells metric screws and bolts but they are very expensive. What's weird is that they sell bolts in packs of 5 and nuts in packs of 3. Go figure. People don't realize how expensive it is to keep two systems in parallel in modern time with growing international trade and Internet. What is interesting is that Americans having European roots did not adopt metric system while Japanese did long time ago. -- Rafael ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
