A mil is 0.001 inch or 0.0254mm.

IMO it is a real problem, now they prefer to go metric with pin spacings,
it is a nightmare.
If only _some people_ had accepted metric measurements ASAP we might not
have to deal with the mess now.

My PCB software has nm resolution, but it is still a pain with grids and
routing.
