Anyone off to VCF-UK

I have no problem with them at all.... I am certainly happier doing metalwork in 'thou' (1/1000 inch) than fractions of a millimeter [1]. But I can work with just aobut any units -- converting them to something I know is not exactly difficult. [1] I do find it amusing that my supposedly metric set of feeler guages has the 2 thickest blades 0.38mm and 0.63mm.I assume everyone gets that... The comment that imperial units are difficult to convert between is IMHO irrelevant for most people (and those who do need to worry about it can geenrally do the calculation). So you don't know how many inches there are in a mile (63360 I think). Most people never need to do that conversion. You use miles to work out how far it is to get to the VCF and inches to lay out the PCB you're taking to the VCF. I personally do not like 10 as a base of a number system or unit system. Systesm based on powees of 2 seem a lot more convneinet. And there are rather mroe powers of 2 in the imperial system. But as I said I can work in any units (provided I can find a conversion factor to something I know). -tony
