Here is one case where I hand-edit the source files and set up a spreadsheet to calculate the exact locations based upon metric calculations. By doing this, errors in conversion are minimized, not multiplied. This gets things accurate to within 1/10,000th of an inch (actually within 1/20,000th of an inch), which is way more precise than pick and place machines or even the tolerance of the etching process.

The only thing I can do is select a grid size in mils that, once drawn, "more or less" lets the pads in te right place. It gets harder when using a long pin strip. Or am I missing something? How would you draw a SIL pinout for a component with 20 pins 1mm apart? I've had to use a really fine grid and do some rounding... Hope there's a better approach!
