I've never seen or heard of one that used 'thou'. For the benefit of those unfamiliar with the term, 'thou' is defined as: an alternate name for what Americans call a mil: a unit of distance equal to 0.001 inch (25.4 micrometers). This name originated in Britain, but it is now common in the U.S. also. - http://www.unc.edu/~rowlett/units/dictT.html (University of North Carolina) So although I accept (from our discussion here) that 'mil' appears to be more widely used than 'thou', my (British) engineering background means that 'mil' is 'millimetres' first, 'milli-inch' second. It's like the word 'pants', which to me is underware first (UK meaning), and an outer garment for the lower part of the body second (US meaning). I could avoid this issue altogether by using my preferred measurement system, which is metric. However when I switch kicad to metric I get unfriendly grid choices, such as 0.127mm. Since it looks like 'mil' is more widely used to mean thousandths of an inch, is there a way of getting kicad to give me rational metric grid options, so I can work purely in metric without immediately hitting a brick wall? BTW, this US vs UK vs the world business leaves a bad taste in the mouth. This isn't a battle, it's a matter of the same word having different meanings in different parts of the world.

Another small thing, how do I turn on snap-to-grid feature in PCBNEW? TIA Yep the ruler is called Add Coatation and it is on the right menu. Do not use it on copper layers . The display metric or imperial depends on the mm or inch tools on the left menu. There isn`t any Undo feature implemented yet i think , but there is Undelete function . Snap to grid and snap to electrical grid is default turned on. I think that it cannot be turned off exept for magnetic pads which is from the Preferences -- General options menu. Cheers
In Schematic, the Capacitor (Polarised) - known as CP is a symbol that I am not familiar with. It's a dark box inside a sort of shield. Is the dark box +ve? - Thanks.
Heh. It was unfamiliar to me too, so I just created a new capacitor using one of the symbols I recognise.
