Z scale calculations - rules of thumb... Most z-scalers used to the metric system are probably familiair with this one: How do you get from z-scale centimeters to 1:1 meters? - double - add 10% How so? well: for example 3cm in Z >> 2x3=6 >> +10%=6,6 meter; check: 3cm X220=660cm=6,6meter) This one I ran in tonight and might also be helpful: How do I translate an h0-scale drawing into z-scale measurements? - multiply h0-scale inches by 10 to get z-scale mils How so? well: - inches to mils is to multiply by 25,4 - h0 to z-scale is to multiply by 87/220, or divide by (roughly) 2,53 - 25,4 / 2,53 = 10,044545454... Example: a wall in h0 of 0.12" thickness in z-scale translates to a wall of 1.2mil. Matt
I actually used the metric and inches interchangeably converting on the fly in my 40 year career in Semiconductor Manufacturing. BUT, to this day I have always had problems with centimeters. They were always so alien to me, I cannot instantly tell how tall a person is in cm. I know a 6 foot tall guy is about 183cm tall, but I always converted to mm, since all the machines made in Europe and Asia came setup in meters and millimeters. US built machines were always in inches and mils. So I always converted an inch to 25.4mm, and got pretty good doing it instantly in my head. Also, US Machines used the decimal point as a period "." where European and Asian machines came marked with the comma "," as representing the decimal point. Again, translated instantly in my head. But centimeters... BAH! Translate in my head then divide by 10. Extra math! 2.54cm per inch!
