Hello All, The company I work for has be metric for years. However printed circuit boards are still laid out in English units. I think this is because Integrated circuit packages have traditionally be designed in Inches. Integrated circuit die are now talked about in gates per square millimeter. I am reminded about 20 years ago someone asked a mechanical engineer on a project I was working on "how big is the long side of an E size drawing?" he responded " about 1 Meter 4 inches". Generating a comfortable feel for metric takes time. As an electrical engineer I have a good feeling for small distances since I have been looking at oscilloscope screens that have metric gradicules for about 35 years. We had a mechanical designer with about 45 years drafting experience who could freehand draw any length under an inch within a few mil (0.001"). Metric and English are confusing but the conversion is more or less constant. Currency conversion however varies country to country, day to day, and where you get your money converted. By using master or visa card you can just spend it and let the next statement figure it all out.
